What are the domain and range of the piecewise function below?

Step-by-step explanation:

Given is a graph of a piecewise funciton

Domain is the set of all values x can take

Here we see that the lowest value of x starts from -6 excluding -6 and goes upto -2 exclusing -2.

From 2 onwards x takes all values without break upto infinity.

Hence domain =

Range:

Range is the set of all values that y can take.

We see from the graph that y takes values from 4 to 8 excluding end values and then continuous values from -1 to 1.

Range =

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
