Negative:

Step-by-step explanation:

The graph represents a parabola that has a maximum vertex at (1,4).

The portion of the graph above the x-axis is considered positive

For , the function is positive.

We can write this in interval notation as:

For or , the function is negative.

We can write this in interval notation as:

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
