Question

Paula bought a 5-pound bag of granola. She plans to use equal amounts of granola to make 10 bags of trail mix and add the remaining amount to her bird feeder. She created the given function to model the amount of granola, in ounces, that she can add to her bird feeder if she puts x ounces in each bag.
What is the range of the function?
A. all whole numbers between and including 0 and 8
B. all whole numbers between and including 0 and 80
C. all real numbers between and including 0 and 80
D. all real numbers between and including 0 and 8

Answer 1

Given function: P(x) = -10x + 80.

Where function represents the amount of granola, in ounces and x represents the number of ounces Paula puts in each bag.

Range of the function is the values of the function we would get.

That is the amount of granola in ounces for different x values.

For x=0 the number of ounces would be -10(0)+80 = 80.

And for x=8, it would be -10(8) + 80 = 0.

But even we could take decimal values too.

Like x=0.5 ounces, x=0.55 ounces etc.

And that 0.55 would give a decimal value.

Therefore, we can take any real number for x between 0 and 8.

But we need to find the range.

So, the range would be between 0 and 80 and it could be any real number.

Therefore, correct option is :

C. all real numbers between and including 0 and 80.
