Answer:
(59) = 20
Step-by-step explanation:
(x) is the inverse of f(x)
to find the inverse function, let f(x) = y and rearrange to make x the subject.
y = 3x - 1 ( add 1 to both sides )
y + 1 = 3x ( divide both sides by 3 )
= x
change y back into terms of x with x = (x) , then
(x) =
, then
(59) =
=
= 20
The pattern shows multiplication because the earnings are 12 times the number of hours worked in each pair of values.
We are given a graph. The graph shows the number of hours worked versus the earnings in dollars. The values of the x-coordinates are 0, 1, 2, 3, 4, and 5. The corresponding values of the y-coordinates are 0, 12, 24, 36, 48, and 60. We need to find the pattern among these values.
We can see from the data that the values are in a straight line in the graph. The coordinates have the same proportion. The constant of proportionality is calculated below.
k = 12/1 = 12
Hence, the pattern is multiplicative because the earnings are 12 times the number of hours worked for each pair of values.
