Answer correctly for brainliest

f(x) = x^2 + 2x + 1

To find f(-7), all we need to do is plug in -7 everywhere there is an x. Then, we simplify to find our numeric answer.

f(-7) = (-7)^2 + 2(-7) + 1

= 49 - 14 + 1

= 35 + 1

= 36

f(-7) = 36

Hope this helps!! :)

f(x) has value 150 at x= 0

and 0 at x= 3

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