Here are the true statements:
The 6 in the third term is a coefficient. It is paired with a variable so it is a coefficient.
The y in the third term is a factor because it is being multiplied by (6x + 7).
The 9 is a constant because it is just a number in the second term.
X intercept: (-4)
y intercept: (8)
1.15¹⁰=4.0456, the growth rate, so the increase is 3.0456 or 305%.
The answer to the question is 14
x^4 + 14x^2 + 49
(x^2 + 7)^2
perfect square
