Question

The functions f(x) and g(x) are described below: f(x) = 3x − 7 g(x) = 3x + 8 The graph of g(x) is obtained by shifting up the graph of f(x) by _____ units. Numerical Answers Expected!

Answer 1

15 units

Explanation:

In algebra, when adding constants (non variable numbers) to a linear function shifts up. Similarly, when subtracting them, the graph shifts down. Here, the graph of g(x) shifts up f(x) by 15 units, because 3x-7+15 = 3x+8.
