Step-by-step explanation:

We just have to find the sums of the product of Joey's averages and their contribution to the total grade.

Test: 0.45 * 0.8 = 0.36 = 36%

Quizzes: 0.3 * 0.85 = 0.255 = 25.5%

Homework: 0.25 * 0.65 = 0.1625 = 16.25%

Total: 36% + 25.5% + 16.25% = 77.75%

The value of g(x) = 2[f(x)]² - 1 is g(x) = 8x² + 8x + 1

<h3>How to find a function?</h3>

f(x) = 2x+1

Find

g(x) = 2[f(x)]² - 1

Hence,

g(x) = 2[2x + 1]² - 1

g(x) = 2[4x² + 4x + 1] - 1

g(x) = 8x² + 8x + 2 - 1

g(x) = 8x² + 8x + 1
