Answer:
The values for x are x =0 x = 1/4
Step-by-step explanation:
f(x)=4x^2-x-3
find f(x) = -3
Let f(x) = -3
Solve for x
-3 = 4x^2-x-3
Add 3 to each side
-3+3 = 4x^2-x-3+3
0 = 4x^2-x
Factor out an x
0 = x( 4x-1)
Using the zero product property
0 = x 4x-1 =0
0=x 4x=1
0=x x = 1/4
The values for x are x =0 x = 1/4
