$f(x)=7-x$

Cory Kuzinski · Accepted Answer

were given this function F of X is equal to seven minus X, but we&#x27;re gonna find f of negative three to ready seven minus negative three, which is equal to seven plus three so f of negative three is 10.

and this problem, we&#x27;re given the function F of X is equal to negative for We were asked to find the function value when X is equal to negative three. To do this bacon substitute the value of negative three into X. But in this case, why is a constant? It is equal to four. So the value of that why when x is equal to negative three is for.

Emma Chickles · Answer

and this problem I given the function of f of X is equal to the absolute value of exports to I&#x27;m asked to find the function value when X is equal to negative three. To do this, we can substitute the value of negative three and two ex and the absolute value of negative one is positive one. So the answer is one.

Cory Kuzinski · Answer

f of axes. Negative four acts, but we want to find f of negative three. Okay, that would just be negative. Four times negative three, which is positive. 12 So f of negative three is 12.

Cory Kuzinski · Answer

given the equation Y equals one the square root of one minus acts, and we&#x27;re gonna find the value of this function at input. Negative three. So squared of one minus negative, 31 minus negative. Three is like one plus three. And we know that one plus three is four. And we also know that Square four is to probably showed way more steps than I needed to. It&#x27;s a mental math we could have done there, but the answers to

special wanna find f of negative thoughts. So we&#x27;re just gonna plug whatever numbers inside of these parentheses here in for that variable. So for this first example, we&#x27;re gonna plug in negative vibe, and we were the way, see, X and our function, they just become. Now, you make sure you bring down a negative, an insert negative five for X and then bring down it. Negative. Seven. There. So think of this as, ah, negative. One times negative fives and understood. One made one times negative. Bach. Is this positive? Five minus seven in five months. Seven. Gives us negative, too through. Gonna do the same thing for every negative three. We&#x27;re gonna plug negative three and bricks. So remember, understood. Negative point. Now we&#x27;re gonna plug in negative three for a variable x and bring down that one. A seven negative one times negative. Three gives us positive three. Then three months. Seven gives us negative for. We also want to find after 1/2. So negative 1/2 numbering down at minus seven. This would be negative 1/2 minus seven. And when it&#x27;s due common denominators so negative. 1/2 minus. And we need this also have denominator too. So this hasn&#x27;t understood denominator one. So we multiply the top and bottom by two. And we get negative 14 on top. So one minus 14. That gives us negative 15 over, too. Or if you like my extractions. Negative. Seven and 1/2. And lastly, we need to find ever before stood up before it was gonna plug in or everywhere that we see x so negative or minus seven was becomes negative for money. Seven. And that gives us negative 11.
