Our quadratic polynomial function is:
f(x) = 4x^2 + 2x + 5
our linear binomial form is:
x - a = -2
hence:
a = x + 2
and so we have:
f(x) = 4x^2 + 2x + 5
f(a) = 4(x + 2)^2 + 2<span>(x + 2)</span> + 5
= 4(x^2 + 4x + 4) + 2x + 4 + 5
f(a) = 4x^2 + 18x + 25
First we need to find the median of the data given. To do that, it should be in order:
12, 15, 18, 20, 23, 23, 28
So the median is 20
The only way to guarantee that the median doesn't change would be for the eight hour to have 20 visitors so the new data would be:
12, 15, 18, 20, 20, 23, 23, 28
Hope this helps!
Answer:
Step-by-step explanation:
The highest power of x here is 3, so this is a third degree polynomial. Since the coefficient of the highest power term is +, we know that the graph approximates that of the parent function y = x^3, and that this graph begins in Quadrant III, enters Quadrant I and continues to move upward in Quadrant I.
