Question
Write the equation of the transformed function 
when the function is vertically stretch by a scale factor of 6.
- g(x) = 3x + 3
- g(x) = 3x + 18
- g(x) = 3x - 18
- g(x) = 3x - 3
Hint:
Vertical stretch is a multiplication of the constant factor with the given function.
The correct answer is: g(x) = 3x + 18
Given That:

Ramona’s garage charges the following labor rates. All the customers are charged for at least 0.5 hr.
Write the linear function for the data in the table.
A linear function forms a straight line in a graph. It is usually a polynomial function with a degree of 1 or 0, and the equation f(x) = mx + b, where b and m are real numbers. Isn't it similar to the slope-intercept form of a line, which is written as y = mx + b? Yes, because a linear function represents a line.
¶Examples from daily life
1. To print logos on T-shirts, a t-shirt company charges a one-time charge of $50 and $7 per T-shirt. As a result, the total cost is given as a linear function f(x) = 7x + 50, where 'x' is the total number of t-shirts.
2. In linear programming problems, linear functions represent an objective function to minimize costs or maximize profits.
