What is the y-intercept of the function f(2)=4-5x?
-5
-4
4
5

C. 4

First, rearrange the equation into slope intercept form, which is y = mx + b, where m is the slope and b is the y-intercept. You get y = -5x + 4. This means the y-intercept is 4.

For this case we have a function of the form

Where:

To find the y-intercept of the function we must do x = 0.

Then, replacing:

So, the y-intercep of the function is 4

4

Option C

(a) the volume of the cone is 20/3 in3

hence, option a is correct.

-2 is the right
