Function B increases at a faster rate. The rate of change for A is 1. The rate of change for B is 1.5.

In order to find the rate of change for each so that we can compare, we need to use the following formula.

Change = (y2 - y1)/(x2 - x1)

In which (x1, y1) is the original point (x = 2) and (x2, y2) is the second point (x = 3). So, let's use the equation for each set of points.

FUNCTION A

Change = (y2 - y1)/(x2 - x1)

Change = (0 - -1)/(3 - 2)

Change = 1/1

Change = 1

FUNCTION B

Change = (y2 - y1)/(x2 - x1)

Change = (0 - -1.5)/(3-2)

Change = 1.5/1

Change = 1.5

While testing a new pesticide, an agricultural scientist uses two functions to predict the yields of two same-sized potato farms
Pepsi [2]

Answer:

A. h(x)= -5.86x^2 + 23.37x + 34

Step-by-step explanation:

If the scientist uses the same amount of pesticide on the two farms then the x's of the functions are the same.

Then, the combined yield h(x) of the two farms is just the yield of the first farm plus the yield of the second farm:

h(x)=f(x)+g(x).

Now, since

f(x)= -2.43x^2+10.37x+9

and

g(x)= -3.43x^2+13x+25,

then

h(x)= (-2.43x^2+10.37x+9)+(-3.43x^2+13x+25)

we add the coefficients of the  corresponding terms to get:

h(x)= (-2.43x^2-3.43x^2)+(10.37x+13x)+(9+25)

\boxed {h(x)=-5.86 x^2 + 23.37 x + 34.}

Which is choice A.
