Can someone help me find identify the range?

=====================================================

Explanation:

The idea is to plug in the smallest value of the domain, which is x = 1, to get

f(x) = -2x+5

f(1) = -2(1)+5

f(1) = 3

Showing that y = 3 is the largest value in the range. Any larger x value produces a smaller y value. Eg: x = 2 leads to f(2) = 1

So the range is the set of y values such that which converts to the interval notation . This is the interval from negative infinity to 3.

The square bracket says to include the endpoint while the curved parenthesis means we exclude the endpoint. We always exclude infinity as we can't ever reach it.

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
