Step-by-step explanation:
Set up the proportion
x/75 = 2304/900 cross multiply to get 900x = 172800
172800 ÷ 900 = 192
x = 192

Answer & Step-by-step explanation:
When using piecewise functions, the intervals represents what function will be used when given a certain number. So, let's begin.
For f(-3), we will use the first function because -3 is less than -1.
<em>f(-3) = 7/2 + 2(-3)</em>
<em>f(-3) = 7/2 - 6</em>
f(-3) = -5/2
For f(-1), we will use the first function again because -1 equals -1.
<em>f(-1) = 7/2 + 2(-1)</em>
<em>f(-1) = 7/2 - 2</em>
f(-1) = 3/2
For f(3), we will use the last function because 3 equals 3.
<em>f(3) = 1/4(3)</em>
f(3) = 3/4
