If:
find g(3b). In this problem, you'd literally plug the 3b into the equation. Let's do that:
We can further simplify this by pulling out a 3 and a "b":
So, your answer is g(3b) = 3b(b-1).
Answer: Because the a-value is negative.
<u>Step-by-step explanation:</u>
The vertex form of a quadratic equation is: y = a(x - h)² + k where
- "a" is the vertical stretch
- -a is a reflection over the x-axis
- h is the horizontal shift (positive = right, negative = left)
- k is the vertical shift (positive = up, negative = down)
Given: g(x) = - (x + 1)² - 3
↓
a= -1
Since the a-value is negative, the parabola will be reflected over the x-axis which will change the curve from (U-shaped) to (∩-shaped).
Answer: -1 and -3/4 (-0.75)
Step-by-step explanation: -1 + -3/4 = -1 3/4
Answer:
432ft²
Step-by-step explanation:
A = π(12)²
A = 144π = 432
