Question

If g(x) = ax2 + 3x – 5, what does a need to be so that...

g(-1) = - 15

(If at all possible please provide steps or an explanation)

Answer 1

Answer:

Step-by-step explanation:

g(x)=ax²+3x-5

then g(-1)=-15

therefore g(-1) ⇒ a(-1)²+3(-1)-5=-15

a-3-5=-15

a-8=-15

a=-15+8

a=-7

for g(-1)=-15

then g(x)= -7x²+3x-5
