Answer:
Value of h(2y+6) = -18y -57
Step-by-step explanation:
Given the function rule:
h(u) = -9u -3 ......[1]
To find h(2y+6)
Substitute u = 2y + 6 in [1] we get;
h(2y+6) = -9(2y+6) - 3
Using distributive property: [tex]a\cdot (b+c) = a\cdot b + a\cdot c[/tex]
h(2y+6) = - 18y - 54 - 3 = -18y - 57
Therefore, the value of [tex]h(2y+6) = -18y - 57[/tex]
