Question

This is a bit hard and I’ve tried multiple times and still don’t get itA. F(1)B. F(-4)

Answer 1

a) f(1) = 2

b) f(-4) = -13

Step-by-step explanation:

Given the below function;

`f(x)=-x^2_{}+3`

a) To determine the value of f(1), we have to substitute x with 1 in the function and perform the indicated operations as seen below;

`f(1)=-(1)^2+3=-1+3=2`

b) To determine the value of f(-4), we have to substitute x with -4 in the function and perform the indicated operations as seen below;

`f(-4)=-(-4)^2+3=-16+3=-13`
