Answer:
Step-by-step explanation:
Please write y = x^2. The " ^ " symbol indicates exponentiation.
Here's how we get from the graph of y = x^2 to the graph of y = x^2 + 8:
Graph y = x^2. Now translate the entire graph 8 units up.

Answer:
Discontinuity: x = -3 and x = 3
Zero: x = 0
Step-by-step explanation:
We know that a function is discontinuous, when the denominator of the function is 0. So let's see what the denominator equals.
x2 - 9 = 0
+9 = +9
x2 = 9
x = + 3
Now lets find the zeros of the function by substituting y = 0 in the function.
0 = 3x/(x2 - 9) (x2 - 9)
0 = 3x
0/3 = 3x/3
0 = x
This means that the function is discontinuous at points x = -3 and x = 3. the zero of the function x = 0.

Answer: For 10 sessions, the cost of the two plans the same.
Step-by-step explanation:
Let x= Number of sessions.
Given: Christian’s Gym charges a one-time fee of $50 plus $30 per session for a personal trainer.
Total charge for x sessions = 50+30x
Nicole's fitness center charges a yearly fee of $250 plus $10 for each session with a trainer.
Total charge for x sessions = 250+10x
When both plan charges the same, then
i.e. For 10 sessions, the cost of the two plans the same.
