well, we know the piece-wise function is 
hmmm so what's f(-1), namely what is f(x) when x = -1?
well, when x = -1, hmm -1 is less than 0, so the subfunction that applies to that will be when "x" is less than 0, namely the part of 7x + 10, so we can say
f(-1) = 7(-1) + 10
f(-1) = 3
so hmm what's f(0) or namely, what's f(x) when x = 0?
well, what subfunction applies when x = 0? well, it has to be the subfunction with "x greater or <u>equals</u> to 0", x ⩾ 0, so then is 7x + 20
f(0) = 7(0) + 20
f(0) = 20.
The perimeter of a rectangle is 10x + 2 which is a polynomial function. Option C is the correct answer.
<h3>
What is a perimeter?</h3>
A perimeter is a closed path that outlines either a two-dimensional shape or a one-dimensional length.
Given that the length is 3x+2 and the width is 2x-1. The perimeter of a rectangle is given below.
A polynomial function is a function that involves only positive integer exponents of a variable in an equation.
Hence we can conclude that the perimeter of a rectangle is 10x + 2 which is a polynomial function. Option C is the correct answer.

A gram is 1/1000 of a kilogram. 3/5 of a gram is .6/1000 kilograms
A kilogram is 1000 grams, 1/5 of a kilogram is 200 grams.
1/5 of a kilogram is heavier.
