<h2>Answer:</h2>

The following which represents the graph becoming more narrow is:

B. kf(x)

<h2>Step-by-step explanation:</h2>

We are given a parent function f(x) as:

$f(x)=x^2$

and k=3

Now, we know that the transformation of the type:

f(x)+k

shifts the graph of the function k units upward while there is no change in the shape of graph.

Similarly the transformation f(x+k) and f(x-k) shifts the graph of the original function k units to the left and k units to the right but odes not change the shape of the function.

Hence, the answer is:

B. kf(x)

Since, the transformation is a vertical compression and the graph becomes more narrow.

<span>The only type of transformation that can make a graph more narrow/wide is a scaling transformation. A scaling transformation involves a multiple factor. The answer to your question is B. </span>I hope that this is the answer that you were looking for and it has helped you.

Answer: D) 32

Step-by-step explanation:

The area of a parallelogram equals its base times its height. Substitute the base and area into this formula to solve for the height:

A=bh

40=(5)(h)

h=8

If ABCD is a parallelogram, opposite sides are parallel, so AB is parallel to DC. If AB is parallel to DC, EB is parallel to DC. Since EB is parallel to DC, quadrilateral EBCD has at least one pair of parallel sides, making it a trapezoid. The area of a trapezoid is equal to $\frac{h(b_{1}+b_{2}) }{2}$ where h is the height, $b_{1}$ is one base, and $b_{2}$ is the other base. Plug the necessary values into the formula:
