Answer:
ax²+bx+c
Step-by-step explanation:
where a is the coefficient of x²
b is the coefficient of x
and c is a constant
Where a,b,c is any real number
Step-by-step explanation:
For this composition function,
, we should substitute
anytime we see an
variable in
:
![x^{2} + 1](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%2B%201)
![[g(x)]^{2} + 1](https://tex.z-dn.net/?f=%5Bg%28x%29%5D%5E%7B2%7D%20%2B%201)
![(3x)^{2} + 1](https://tex.z-dn.net/?f=%283x%29%5E%7B2%7D%20%2B%201)
![9x^{2} + 1](https://tex.z-dn.net/?f=9x%5E%7B2%7D%20%2B%201)
Answer:
f(2) = -1
Step-by-step explanation:
Looking at the graph, there appears to be two points at x = 2. However, looking more closely, we see that the point (2, 4) is empty; this means the graph goes up to this point but does not hit this point.
The point (2, -1) is filled in; this means the graph hits this point.
