Answer:
g(x) = f(x) + 18
Step-by-step explanation:
Answer:
See below
Step-by-step explanation:
I assume you mean 
The equation is already in vertex form
where
affects how "fat" or "skinny" the parabola is and
is the vertex. Therefore, the vertex is
.
The axis of symmetry is a line where the parabola is cut into two congruent halves. This is defined as
for a parabola with a vertical axis. Hence, the axis of symmetry is
.
The minimum value is the smallest value in the range of the function. In the case of a parabola, the y-coordinate of the vertex is the minimum value. Therefore, the minimum value is
.
The interval where the function is decreasing is 
The interval where the function is increasing is
I hate dividing fractions but I think -2/16 off of my best hunch.
20 + 2*(3-5)^2 + (30/10)*3
20 + (2*[-2])^2 + (3*3)
20 + (-4)^2 + 9
29 + 16
45
Note that * is used to signify multiplication.
