Kyle's Functions
Mr. Hawkins gave Kyle two quadratic functions to compare.
Function 1
f(x) = -(x-1)^2+9
Function 2 (Its a Table)
x | g(x)
-1 | 0
-0.5 | 3.75
0 | 6
0.5 | 6.75
1 | 6
1.5 | 3.75
2 | 0
QUESTIONS:
Part 1
from "Kyle's Functions"
What is the difference in distances between the x-intercepts of f(x) and g(x)?
A. 1 unit
B. 2 units
C. 3 units
D. 4 units
Part 2
from "Kyle's Functions"
Which statement is true about the maximum values of f(x) and g(x)?
A. The maximum value of f(x) is 0.5 units below the maximum value of g(x).
B. The maximum value of g(x) is 0.5 units below the maximum value of f(x).
C. The maximum value of f(x) is 2.25 units below the maximum value of g(x).
D. The maximum value of g(x) is 2.25 units below the maximum value of f(x).
I think its:
Part 1: D
part 2: C
1 answer
Part 1: D (The difference in distances between the x-intercepts of f(x) and g(x) is 4 units)
Part 2: C (The maximum value of f(x) is 2.25 units below the maximum value of g(x))
