Answer:
- f(x) = 2x -2/3
- f(3) = 5 1/3
Step-by-step explanation:
We solve an equation for a specific variable by using inverse operations to undo what is done to the variable. The resulting function is evaluated by substituting the given value for the variable.

<h3>a.</h3>
We are given the equation ...
6x -3y = 2
Solving for y, we get ...
6x -2 = 3y . . . . . add 3y-2 to both sides
2x -2/3 = y . . . . . divide by 3
f(x) = 2x -2/3 . . . . write using functional notation
__
<h3>b.</h3>
To find f(3), we use x=3 in the function.
f(3) = 2(3) -2/3 = 6 -2/3
f(3) = 5 1/3

Answer:
1. Multiply 6 each time. Equation: 6x = y
2. Multiply 15 each time. Equation: 15x = y
Step-by-step explanation:
Check. Let:
Input = x
Output = y
Put the data into the equation given:
Equation: 6x = y
When x = 1; y = 6
6(1) = (6)
6 * 1 = 6
When x = 2; y = 12
6(2) = (12)
6 * 2 = 12
When x = 3; y = 18
6(3) = (18)
6 * 3 = 18
etc.
Check. Let:
Input = x
Output = y
Put the data into the equation given:
Equation: 15x = y
When x = 1; y = 15
15(1) = (15)
15 * 1 = 15
When x = 2; y = 30
15(2) = 30
15 * 2 = 30
When x = 3; y = 45
15(3) = 45
15 * 3 = 45
etc.
