Answer:
The positions of the vertex and the axis of symmetry change.
Step-by-step explanation:
Let’s examine three parabolas in which a and c remain constant and only b changes.
(1) y = x² - 2x + 1
(2) y = x² + 1
(3) y = x² + 2x + 1
In the image below,
Equation (1) is the black parabola, Equation (2) is green, and Equation (3) is red.
When b is more negative, the vertex moves down, and the axis of symmetry moves to the right.
When b is more positive, the vertex moves down, and the axis of symmetry moves to the left.

First, you need to do the distubutive property, you should get 18m+30=66. Then you could subtract 30 from both sides. Then, you should get 18m = 36. You will then divide both sides by 18. Your answer should be m = 2. Hope this helps!
Answer:
117
Step-by-step explanation:
Got it from calucaltor and did it to make sure
The given data are:
A function that:
The domain is the set of all real numbers
One x-intercept
The amplitude is 4
The y-intercept is (0,0)
From the choices, the functions containing "cosine" can be eliminated since the described function passes through (0,0). So, we are left with two choices:
y = -4sin (x) and y = 4sin (x)
Given the amplitude of 4, the answer must be y = 4 sin(x)
