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

f(x) = 4x − 1

Answer Choices:
a. The function f(x) has a higher y-intercept.
b. The function g(x) has a higher y-intercept.
c. They both have the same y-intercept.
d. The relationship between y-intercepts cannot be determined.

welshfella · Answer

you can find the y intercept by replacing x by 0 and working out the value of f(x)

welshfella · Answer

g(x) - can you see a pattern here so you can find g(x) when x = 0?
