Answer:
h(x) = - 4x² + 5
Step-by-step explanation:
To find h(x) = g(2x² + 1), substitute x = 2x² + 1 into g(x)
h(x) = - 2(2x² + 1) + 7
= - 4x² - 2 + 7
= - 4x² + 5

- Data should be approximately normal with sample size, n being greater than 30 (n ≥ 30).
- The sample selection must be independent, as the outcome of a certain trial must not depend on the outcome of another.
