Question

Which function rule matches the graph below?
f(x) = 3x - 3
f(x) = -1/3x + 3
f(x) = -x² + 3
f(x) = 1/3x +3

Answer 1

The function rules are in y=mx + b form. Where m is the slope of a line and be is the y-intercept. The graph shows a negative slope and a y-intercept of 3.

Answer 2

a

Answer 3

f(x)=3x-3

Answer 4

That can't be right. The graph shows positive 3 as the y-intercept

Answer 5

sorry its D

Answer 6

Yeah, I got D to by plugging in the coordinates (0, 3)
