Answer: FIRST OPTION.

Step-by-step explanation:

Given the following function:

f(x)= 4x + 8

Follow this steps in order to find its inverse:

1. Rewrite the function with y=f(x):

y= 4x + 8

2. Solve for "x":

y-8= 4x\\\\x=\frac{y-8}{4}\\\\x=\frac{y}{4}-2

3. Now you must exchange the variables:

y=\frac{x}{4}-2

4. And finally, rewrite the function with h(x)=y:

h(x)=\frac{x}{4}-2

Therefore, the inverse function is h(x)=\frac{x}{4}-2

Answer:

A. There is not sufficient evidence to conclude that the mean price of a​ single-family home has decreased

Step-by-step explanation:

To study : Whether the mean price of single family home has decreased or not -

Null Hypothesis [H0] = There is no change in mean price of single family home

Alternate Hypothesis [H1] = There is change (decrease) in mean price of single family home

If the null hypothesis is not rejected, it implies that 'there is no change in mean price of single family home' has been statistically accepted.

So, it states that - There is not sufficient evidence to conclude that the mean price of a​ single-family home has decreased
