Hi, today we are solving the question in which we are given with the function f of x is equals to minus 3x into root x plus 1.
00:13
So, here we need to find two intercepts of the function of f.
00:18
So, first of all to find the x intercept we need to find the x values.
00:25
So, when f of x is equals to 0.
00:29
So, from here minus 3x into root x plus 1 is equals to 0.
00:35
Now, let us solve for x.
00:38
So, if we consider it from here we can take it as 1 is equals to 3x into root x and dividing both sides by 3 we can take it as 1 by 3 is equals to x into root x.
00:58
Now, squaring both sides we get 1 by 9 is equals to x square taking the square root of both sides we get x is equals to 1 by 3.
01:10
So, there is only one x intercept that is x is equals to 1 by.
01:23
Now, finding a value of x such that f dash x is equals to 0...
