Question

Select the table that represents the function f(x) = 3x + 5

Answer 1

the function f(x) = 3x + 5 has a slope of 3 and a y-intercept of (0,5).

Table 1, reproduced below, shows that for every unit increase in x, y increases by 3, and that y=5 when x=0 (which is the y-intercept).

Table 1 is the correct answer.

-3 -4

-2 -1

-1 2

0 5
