Answer:

Step-by-step explanation:

Input values must have exactly one output value in order for the function to remain a function.
d. 2
f. 8
g. 15
The graph of an absolute value parent function is a pair of rays in quadrant 1 & 2, as shown in the graph.
The absolute value function is
f(x) = |x| or y = |x|
We also know that the absolute function can be wriiten as
y = |x|
=> y = x or y = -x
Comparing with y = mx + c
We get
m = 1 or m=-1 and c = 0
c = 0 implies that the line passes through the origin.
Hence the slopes shall be -1, 1 & the line passes through the origin.
Option A, B & D are the right answers.
I got 11 Mexican and 16 American.
20 x 11 = 220
15 x 16 = 240
Which equals 460
