Answer: 30.5
Step-by-step explanation:
A) domain: [ -5 5 ] range: [ -10 -2 ]
b) y intercept: -2 x intercept: -2 2
c) y= -2
d) x= -2 x= 2
e) None
28x + 8y + 2 is the simplified version.
When a zero of a function does not cross the x-axis but touches it, this means that the zero is a "double root". It has two of the same factor (x - 4)^2 and two of the same zeros, x = 4 and x = 4
f(x) = x^2 - 8x + 16 would be the function with a double root at 4
