ElenaW [278]

Answer: The snack shop sells granola bars for a lower price.

Step-by-step explanation:

First you should plug in the number of bars for each equation, if you get one bar from the snack shop the price would be $1.25, I'm going to fill in the table to help you better understand.

y= 1.25(2) 2.50

y= 1.25(3) 3.75

y= 1.25(4) 5.00

y= 1.25(5) 6.25

This table was all for the snack shop.

Given a polynomial function f(x), describe the effects on the y-intercept, regions where the graph is increasing and decreasing,
alina1380 [7]

Answer:

We are have the function f(x).

Part 1: It is given that the function f(x) is transformed to f(x)+2.

This gives us that the function is translated 2 units upwards.

As, the y-intercept of f(x) is f(0). So, the y-intercept of f(x)+2 is f(0)+2, which is also translated 2 units up.

Translation does not change the behavior of the function.

So, if f(x) is increasing (or deceasing), then f(x)+2 will be increasing(or decreasing) respectively.

Moreover, f(x)+2 will be even or odd if f(x) is even or odd respectively.

Part 2: It is given that the function f(x) is transformed to \frac{-1}{2}f(x)

This gives us that the function is shrinked vertically by a factor of \frac{1}{2} followed by a reflection across x-axis.

Also, the y-intercept of is \frac{-1}{2}f(0).

The graph of f(x) after changing to \frac{-1}{2}f(x) will flip over the x-axis.

So, the function \frac{-1}{2}f(x) will increase or decrease when f(x) decrease or increase respectively.

Moreover, \frac{-1}{2}f(x) will be even if f(x) is even or odd respectively.
