Answer:

Step-by-step explanation:
we have

To find out g(x+h) substitute the variable x by the variable (x+h) in the function g(x)
so


Evaluate

we have


substitute in the expression




therefore

<h2>g = -27</h2>
Step-by-step explanation:

Simplify

Cross Multiply

Answer:
B
Step-by-step explanation:
since y and x vary directly the equation relating them is
y = kx ← k is the constant of variation
to find k use any ordered pair from the list given
using x = 4 when y = - 2, then
k =
=
= - 0.5 → B
