Answer:

81.39% increase.

Step-by-step explanation:

Given: There is change in number from 43 to 78.

First lets find the amount of change or difference in number.

Difference in number= $78-43= 35$

∴ Difference in number show that there is an increase of 35 number.

Now, finding the percent change in the number.

Percent= $\frac{Difference\ in\ number}{base\ number} \times 100$

⇒ Percent change in number= $\frac{35}{43} \times 100= 81.39\%$

∴ 81.39% increase in the number.

Kobotan [32]

To check the decay rate, we need to check the variation in y-axis.

Since our interval is

$-2We need to evaluate both function at those limits.At x = -2, we have a value of 4 for both of them, at x = 0 we have 1 for the exponential function and 0 to the quadratic function. Let's call the exponential f(x), and the quadratic g(x).[tex]\begin{gathered} f(-2)=g(-2)=4 \\ f(0)=1 \\ g(0)=0 \end{gathered}$

To compare the decay rates we need to check the variation on the y-axis of both functions.
