With the information given, we deduce that the parabola is
Reflecting a function over the x axis means to change its sign. After the reflection, the parabola becomes
And to shift down a function, you subtract the shift from the equation: the equation becomes
Similarly, the other function is reflected over the x axis (sign change) and shifted up 3 (add 3 to the equation):
In order to compute the y intercept, we simply have to evaluate the functions at x=0: for the parabola we have
For the other function, we have

Squaring both sides of the given equation: w^2=7w, or w^2-7w=0.
w^2-7w=0 can be factored: w(w-7)=0. Then, w=7 or w=0. Both 0 and 7 are solutions of this equation.
Answer:
7.5 or 15/2 (Whatever form you need to use)
Step-by-step explanation:
N-5 divided by 2 =5
Combine like terms:
-5 divided by 2= -2.5.
N-2.5=5
Add -2.5 from itself, then do the same to the other side:
N-2.5=5
+2.5=+2.5 (Adding 2.5 to -2.5 cancels it out)
N=7.5
