plz answer fast, no spam or I'll report .​

Answer 1

Answer:

f(x)=4x+3-0=4x+3

f(0)=4(0)+3=3

f(-1)=4(-1)+3=-1

=f(0)+3f(-1)

=3+3(-1)

Answer 2

Step-by-step explanation:

f(x) =-x²-3x-5

f(0) =- (0)²-3(0)-5 =-0-0-5 = -5

f(1) = -(1)-3(1)-5 = -1-3-5 = -3-5 = -8

f(2) =-(2)-3(2)-5 = -2-6-5 = -4-5 = -9
