Answer:
C = 25 + 50h
Step-by-step explanation:
cost for zero hours is $25, so that is the y-intercept of the graph.
each hours adds a cost of $50, so that is the gradient of the graph. These two values give us our equation in slope-intercept form.
I think n=4 is the answer
Your given expression has no "b", so you can rule out selections b, c, e.
The expression is not equal to 1, so you can rule out selection a.
That leaves selection d, which is the correct choice:
... d. 1/x^a
