Can you teach me how to show work for these questions:

If f(x)=3x+3, g(x)=4x^2-6x+3, and h(x)=5x^2-7, find the following.

53. f(4)



54. f(-1)



55. h(-3)



56. h(0)



57. g(2)



58. g(1)



59. g(0)



60. h(-2)

Respuesta :

just put the following value for x and solve.

53. f(4) = 3(4)+3
= 12+3 => 15

54. f(-1) = 3(-1) +3
= -3+3 => 0

55. h(-3) = 5(-3^2) -7
=5*9 -7
=45-7 => 38

do same thing for others
