Part a)
a) The given function is

We let

Interchange x and y.

Solve for y;



Part b) The range of f(x) refers to y-values for which f(x) exists.
The range of f(x) is

This is because the function is within y=-3 and y=3.
c) The range of

is

The domain is -3≤x≤3
This is because the domain and range of a function and its inverse swaps.
Part d) The graph is shown in the attachment.
Answer:
A
Step-by-step explanation:
Since m∠JOK is 1/5th of the measure of the full circle (we know this because 72° is 1/5th of 360° and 360° is the measure of the whole circle), we know that the measure of minor arc JK will be 1/5th of the circumference of the circle. C = 2πr and we know that r = 5 so the circumference is 10π. 1/5th of that is 2π.
Answer:
Not normal, because we expect fewer than 10 children to redeem the coupon.
Step-by-step explanation:
The original price was $500
First we find 15% of what is $75
15/100 x N =$75
n = $7500/15
n = $500
Answer:
The widths of the shed doorways follow the pattern of multiplying by two. For example, 2 x 2 = 4.
Step-by-step explanation:
