Question

Which function is represented by the graph?

A) f(x) = 2x + 6

B ) f(x) = - 2x + 6

C)f(x) = 1/2 * x + 6

D ) f(x) = - 1/2 * x + 6

Answer 1

f(x) = -

2

x + 6 is correct. Determine the x intercept, set f(x) = 0 and solve for x; -

2

x + 6 = 0; x = 12. Determine the y intercept, set x = 0 to find f(0); f(0) = -

2

x + 6 = 6. the graph of the function is a line passing through the points (12 , 0) and (0 , 6).

Explanation:

Answer 2

I believe it is B because the y intersect is +6 and they slope is going down so it is -2
