Answer:

f(-1) = 4

Explanation:

Using the Quadratic Formula
x=(-b+√(b^2-4ac) )/(2a), (-b-√(b^2-4ac) )/(2a) our Polynomial to find our zeros values on the x-axis.

Any other factoring method that you can think and do can also work.

To find our (h,k) or origin we use this formula
h=x=-(b)/(2a) and then plug our h=x into the equation to get out k.

To find our y-intercept. Plugin x = 0 into the equation to get y.

I used the internet to factory your equation f(x) and got
f(x) = 2(4x+3)(x-1)

x = -3/4 , 1

Substitute -1 into the equation to solve f(-1).

f(-1) = 8*(-1)^2 - 2*(-1) - 6 = 8 + 2 - 6 = 4

f(-1) = 4
