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

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

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
