Question

Two linear functions are shown. Which function has the greater initial​ value? and what is the function of Function A?

Answer 1

Function A

Explanation:

Lets plug in the same x values used in Function A into Function B to determine the answer. Assuming -1 is the initial.

[Plug in values]

y = 3(-1) + 4 = -3 + 4 = 1

y = 3(0) + 4 = 0 + 4 = 4

By inspection, the y value when x = -1 in A is 12, which is bigger than 1 in Function B.
