Question

If f(a) = 3a – a2, which of the following are not true statements?

Answer 1

Answer:

f(-1) = 2

f(0) = 3

Step-by-step explanation:

f(a) = 3a - a²

f(4)= 3*4-4²= -4 ⇒ correct

f(3)= 3*3-3²= 0 ⇒ correct

f(-1) = 3*(-1)-(-1)²=-3+1= -2 ⇒ incorrect

f(0) = 3*0-0²= 0 ⇒ incorrect

f(-5) = 3*(-5)-(-5)²= -15-25= -40 ⇒ correct
