Question

The functions f (x) = 1/2x-3 and g(x) = -2x+ 2 intersect at x = -2. True or false?

Answer 1

9514 1404 393

Answer:

  False

Step-by-step explanation:

f(-2) = (1/2)(-2) -3 = -1 -3 = -4

g(-2) = -2(-2) +2 = 4 +2 = 6

The function values are not the same at x=-2, so the graphs do not intersect there.

The graphs intersect at x=2.
