Can someone please help me and explain how to do it

127

Step-by-step explanation:

so h(g(-5)) means that solve the function in a specific way. This means that solve for function h but the x is the answer to function g when x is -5. So first what u do is solve for g. Plug -5 in so u get -5-3 which is -8. Then u plug in -8 to function h. U have 2(-8)^2-1. Then u solve the square which is 64. Then u multiply that by 2 to get 128. Then u minus one to get ure final answer of 127. Hope this helps :D

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

i believe the answer is letter c) 8
