What is f(−3) for the function f(a)=−2a2−5a+4?

−29
−23

Step-by-step explanation:

f(a)=−2a^2−5a+4

Ler a = -3

f(-3) = -2 (-3)^2 -5(-3) +4

       = -2(9) +15 +4

       = -18+15+4

       =1

Step-by-step explanation:

f(a)=−2a2−5a+4

then

f(−3) = -2(-3)² - 5(-3) + 4

       = -2(9) + 15 + 4

      = -18 + 19

      = 19 - 18

      = 1
