Question

f(x) =12x -3x²- 4 find f(0), f(-1) , f(1/2)

Answer 1

Answer: f(0)=-4

f(-1)=-19

f(1/2)=1/2

Step-by-step explanation:

f(0)=12×0-3×0^2-4

=-4

f(-1)=12×(-1)-3×(-1)^2-4

=-12-3-4

=-15-4.

=-19

f(1/2)=12×(1/2)-3(1/2)^2-4

=6-3/2-4

=2-3/2

=4-3/2

=1/2

Answer 2

Answer:Given that,

f(x)=12x-3x²-4

f(0)=-4

f(-1)=12(-1)-3-4=-12-7=-19

f(1/2)=12(1/2)-3(1/4)-4

=6-3/4-4=5/4

Step-by-step explanation:
