Afunction has an input of -6. what is the output if the function rule is y = 2x - 1?

A function has an input of -6. The output of function is -13

Solution:

Given that function has a input of -6

To find: output of function

Given function rule is y = 2x - 1

The input of the function is "x" and output of function is "y"

By substituting the given input value of "x" in the function rule, we will get the output of function

y = 2x - 1

Plug in x = -6 in above function rule

y = 2(-6) - 1

y = -12 - 1

y = -13

Therefore the output of function is -13

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
