Answer:


h(-6) = -457

Explanation:

Given the function


h(x)= 72 x-25

Put
h = -6 to in the function


h(x)= 72 x-25


h\left(-6\right)=\:72\left(-6\right)-25


=-432-25


=-457

Therefore,


h(-6) = -457

(18)

Answer:


g(2)=25

Explanation:

Given the function


g\left(x\right)\:=\:5x^2\:+\:4x\:-\:3


g\left(2\right)\:=\:5\left(2\right)^2\:+\:4\left(2\right)\:-\:3


= 20 + 8 - 3


= 25

Therefore,


g(2)=25
