Answer:

9 and 4 or D

Step-by-step explanation:

If you're not quite sure how to solve, let's find the answer by process of elimination.

If the area of a rectangle is 36 square inches, we can try option one.

7 * 6 = 42, not 36, so option A is incorrect.

Option two:

12 * 3 = 36 so option B is correct.

Option 3:

10 * 3 = 30 so option C is incorrect

Option 4:

9 * 4 = 36 so option D is correct

Now for perimeter:

9 + 4 + 9 + 4 = 18 + 8 = 26.

12 + 12 + 3 + 3 = 24 + 6 = 30

Thus, an answer of 9 and 4 is correct.

If function f is vertically stretched by a factor of 2 to give function g, which of the following functions represents function
Sunny_sXe [5.5K]

Answer:

A. g(x) = 6|x| +10

Step-by-step explanation:

The parent function is given as:

f(x) = 3|x| + 5

Applying transformation:

function f is vertically stretched by a factor of 2 to give function g.

To stretch a function vertically we multiply the function by the factor:

2*f(x) = 2[3|x| + 5]

g(x) = 2*3|x| + 2*5

g(x) = 5|x| + 10
