Answer:
x = 1
Step-by-step explanation:
Answer:f(x) is the total number of miles he runs during each month. He starts with 0.5 miles and adds (+) 2 miles each month. Therefore, x must be the number of months. For example, month 1 (x) he runs 2.5 miles: 2.5 = 0.5 + 2(1); x=1.

Answer:
x = -0.5 or x = 2
Step-by-step explanation:
Finding solutions graphically is often easier if the equation can be put in the form f(x) = 0. Here, we can do that by subtracting the right-side expression to give ...
(-2x^2 +2) -(-3x) = 0
This could be put in standard form, but there is no need. A graphing calculator can deal with this directly.
The solutions are x = -0.5 and x = 2.
Answer:
Step-by-step explanation:
If we are to find q(p(x)), we are to start at the innermost part of the problem which is p(x). Take the function p(x) and fill it into q(x) every place you see an x:
is the composition of p into q. Now all we have left to do is simplify.
![(3x+4)^2=9x^2+24x+16](https://tex.z-dn.net/?f=%283x%2B4%29%5E2%3D9x%5E2%2B24x%2B16)
Then we have to finally multiply in the 2 to get:
![18x^2+48x+32](https://tex.z-dn.net/?f=18x%5E2%2B48x%2B32)
