Answer:

Step-by-step explanation:
The following piecewise functions are linear functions. The graph of any of them is a line segment.
We just need to calculate the value of the function at each end specified in the brace.

Substitute x =-1 and x = 0:

Range of this piece is [-5; -2)

Substitute x =0and x = 5:

Range of this piece is [3; 13)
Therefore the range of the following piecewise function is:

Look at the picture.
7(x + 1) = 21
7x + 7 = 21
7x = 14
x = 2
Answer:
5/3
Step-by-step explanation:
(5/6)÷(1/2)
= (5/6) x 2
= 10/6 = 5/3

Step-by-step explanation:
<u><em>The correct question is</em></u>
The function f(x) = 3(1.1)^x gives the length (in inches) of an image after being enlarged by 10% x times.
What is the length of the image after it has been enlarged 3 times? Round your answer to the nearest hundredth
we have

This is a exponential growth function
where
f(x) represent the length (in inches) of an image
x is the number of times the image is enlarged
so
For x=3
substitute in the exponential equation
