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

Answer:
a) f(1) = 2
b) f(-4) = -13
Explanation:
Given the below function;
[tex]f(x)=-x^2_{}+3[/tex]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;
[tex]f(1)=-(1)^2+3=-1+3=2[/tex]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;
[tex]f(-4)=-(-4)^2+3=-16+3=-13[/tex]
