Answer: 14</h3>
Explanation:
Pick two columns from the table to form the (x,y) points.
I'll pick the last two columns, since everything is positive here. So we have the points (2, 17) and (4, 45)
Apply the slope formula to those points
m = (y2 - y1)/(x2 - x1)
m = (45 - 17)/(4 - 2)
m = (28)/(2)
m = 14
The rate of change is 14.
What you said doesn't even make sense.
I'll assume you said f(x) = -5x^2 + 4.
This is an even function.
f(-x) = f(x)
100 pens cost x dollars.
Therefore 1 pen costs
x/100 dollars/pen
50 cents = 0.5 dollars. It can purchase
(0.5 dollars) / (x/100 dollars/pen)
= 50/x dollars
Answer: 50 cents can purchase 50/x pens
