Question

Given the following piecewise function,

f(3) =
f(8) =
f(-1) =

Answer 1

f(3) = 5

f(8) = 3

f(-1) = 0

Explanation:

Just plug in the number from the parentheses into the inequalities and whichever makes the inequality true plug into that equation so for example f(3) = ?

first plug 3 into the inequalities: 3 ≤ 0, 0 < 3 ≤ 5, 3 > 5

then find the one that's true which is: 0 < 3 ≤ 5

then plug into the equation that corresponds to that inequality: 2(3) - 1 → 6 - 1 = 5
