Graph h(x)=3cos(2x)−1.

Use 3.14 for π.

Step-by-step explanation:

the answer is in the attachment

1- getting the total cost:
We know that Me will pay:
$905 for parts and $499 for labor cost
This means that:
Total amount paid = price for parts + labor cost
Total amount paid = 905 + 499
Total amount paid = $1404

2- checking using inverse operation:
Assume Meg pays $1404 for her car repairs. This cost includes both the price of parts and the labor cost.
Given that the price of parts = $905:
labor cost = 1404 - 905 = $499

Hope this helps :)
