Which of the following functions is quadratic?

sd

D.

Step-by-step explanation:

Given choices are:

Now we need to find about which of them is the quadratic function.

We know that quadratic function is written in form of

Last choice looks similar to that form.

Hence coorect choice is D.

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
