Answer:
See explanation
Step-by-step explanation:
1. Factor the function 

2. The zeros (or the solutions of the equation f(x)=0) are x=3 and x=5. So? points (3,0) and (5,0) are the points on the graph that are the solutions of the equation.
3. Find the vertex:

Thus, the coordinates of the vertex are (4,2) and the axis of symmetry is the vertical line that passes trough the vertex: x=4.
Answer:
I'm pretty sure it is A
Step-by-step explanation:
Y = how far up
x = how far along
m = Slope or Gradient (how steep the line is)
b = value of y when x=0
How do you find "m" and "b"?
b is easy: just see where the line crosses the Y axis.
m (the Slope) needs some calculation:
m = Change in Y/change in X
Answer:
A point is at negative 0.5 and a bold line starts at negative 0.5 and is pointing to the left.
The number line in Option C.
Step-by-step explanation:
We are given an inequality.

We have to find the number line that shows the solution for the given inequality.
If we solve the given inequality,

is the required solution of the given inequality.
Thus, if we want to plot or show this solution on a number line, then we need to we need to mark the point -0.5 and all the numbers less than -0.5
A point is at negative 0.5 and a bold line starts at negative 0.5 and is pointing to the left.
This s represented in Option C.
