Answer:
Step-by-step explanation:
To find the rate of change of a function, we are looking for it's slope.
We can find the slope of a line by seeing it's rise over run.
Basically - how much the line's y increases divided by how much the line's x increases.
We can see that the y drops from 1 to -1 in 1 x value. This means the change in y is , however in this case it is -2 as we are dropping.
The change in x is 1 .
This means that the slope (rate of change) is .
Hope this helped!

Answer:
B
Step-by-step explanation:
One good way to look at this is to graph both polynomials, as shown in the picture. A tip to help graph is to factor it out and work from there. For example, in x²+14x+48, we can gather that (x+6)(x+8) is the same thing, and it is easier to then graph it. Similarly, for x²+12x+36, we can factor it out as (x+6)² .
When x²+12x+36 approaches 6, it is getting really close to 0, but it stays positive. When x²+14x+48 approaches 6 from the negative side, it is also getting close to 0, but it's negative. When x²+14x+48 approaches 6 from the positive side, it is positive.
Therefore, on the negative side, there is one positive and one negative (dividing a negative by a positive is negative, and a positive by a negative is also negative) , and on the positive side, there are two positives, forming one answer.The answer is therefore B
