That&#x27;s why we didn&#x27;t take some below the ice. And why here and say, why accident? You minus form and equal to one. And then the wily. So you you shouldn&#x27;t have here with the one day and we got a code, you skirt of the 10. Also with the oneness. Well, gonna squirt of tennis. Well, we see that for your crimes under X weakened assembly under Why, I mean, is that this is not a function. Uh oh. Function.

Ali Soave · Answer

it was trading at the Y. Going by itself will start off by subtracting X from both sides. Why cubed is equal to Tony seven minus X. Then we&#x27;ll take the cube root of both sides. Queudrue. These cancel out and why is equal to the cubed root of 27 minus sex? Because every input, every number that we plug in for X will be equal to exactly one output. And yes, this is

Ankit Gupta · Answer

given a function is two X squared minus four by square equals three. Now subtracting two x square from both side of equation Vigour minus four by square equals three minus two X squared. Now dividing throughout the equation by minus full by minus food we get by square equals minus one by food in due three minus two x square which we can write us minus three by four. Plus Do you buy food? X square Now for their simplifying this weekend Writer This X squared by two minus three by full as two by four equals one by two on one by doing two X square is X squared by two. Therefore, we can write this equation as by square equals X squared by two minus three by four Now taking square root to both side of equation we get by equals bless minus route over off X square by two minus three by food. Therefore, as we can see in this last equation that this equation gives value off by for each given value off X Therefore, therefore, we can say that our equation does not defined by as a function off X does not define vie as a function off X since for one value of X, they are getting to values off by

Ankit Gupta · Answer

In the given question, we have met the griffin with one of the girls and here they question it Y squared minus X square is a square to nine. So this can be bitterness y squared up on nine minus X squared up on nine. They save 1/4 1 So this is of article Hi parabola. And the vortex will be at zero comma tree as lead zero Call my industry. So the graph will be this one Were taxi there zero comma three and you don&#x27;t come on my industry And this is dissenter that is zero comma zero.

Ankit Gupta · Answer

given Our function is two X minus four by square equals three. So subtracting two x from both selloff equation We get minus four by square equals three minus two x and now dividing throughout by minus full beget by square equals minus one by food into three minus Twix which can very Dennis minus three by food Plus to buy full X Now we can Right, This is one by two x as two by four equals one by two minus three by four No, we have got our equation. The phone vice square equals one by two x minus three by food. Now we will take square root both side of equation and get by equals less minus root over off one by two x minus three by food. Therefore, here in the last equation, we can see that this last equation gave to values off by for each value off X So we can say that given equation given equation does not defined by as a function off X does not defined by as a function off x
