Question

H(x)=4x2-5X H(-3) what is the answer?

Answer 1

Answer:

H(-3) = 51

Step-by-step explanation:

Put x = -3 to the equation of a function H(x):

$H(x)=4x^2-5x\\\\H(-3)=4(-3)^2-5(-3)=4(9)+15=36+15=51$

Answer 2

Answer:

51

Step-by-step explanation:

H(x)=4x^2-5x

Let x=-3

H(-3) = 4(-3)^2 -5(-3)

Powers first

          = 4(9) -5(-3)

          =36+15

         =51
