Question

F(x) = 70x + 50

g(x) = 22
Which sentence most accurately compares the graphs of the
functions f(x) and g(x)?
Select one
_______________________

•The graph of g(2) will be above the graph of f(x) for all values of x


•At the y-axis, the graph of f(x) is above g(2) but the graph of g(2) eventually
overtakes (2)


•At the y-axis, the graph of g(x) is above f (2), but the graph of f(x) eventually
overtakes g(2)


•The graph of f(2) will be above the graph of g(2) for all values of x

Answer 1

Answer: 4. The graph of f(2) will be above the graph of g(2) for all values of x

1. y is always 22 no matter what x value, g(2) = 22. However f(x) is a linear equation which increases vertically right up, so the y = (-∞, ∞ )

So not accurate

2. f(x) meets y axis at (0,50) while g(x) meets at (0,22), however, g(2) is (2,22) while f(x) is 190.

So not accurate

3. graph g(x) is not above f(2)

4. It is accurate
