Question

Below are two different functions, f(x) and g(x). What can be determined about their slopes?

f(x) Alex earns 1600 dollars in 400 hours.
x g(x)
1 _8
5 12
9 32
The function f(x) has a larger slope.

The function g(x) has a larger slope.

They both have the same slope.

The relationship between slopes cannot be determined.

Can I please get help with this question?

Answer 1

slope of f(x) = 1600/400 = 4
slope of g(x) = (12 - (-8))/(5 - 1) = (12 + 8)/4 = 20/4 = 5

The function g(x) has a larger slope.
