Answer:

Step-by-step explanation:

-20 is to the left on the number line which signifies that it is of low numerical value.

15 on the other hand is to the right on the number line which signifies that it holds still low but greater numerical value.

Hope this helps you and have a great day!

Answer:

$f^{-1}(x)=25(x-2)^2$

Step-by-step explanation:

The inverse function can be found by solving ...

f(y) = x

(√y)/5 +2 = x

(√y)/5 = x -2 . . . . . subtract 2

√y = 5(x -2) . . . . . . multiply by 5

y = 25(x -2)² . . . . . square both sides

The inverse function is ...

$f^{-1}(x)=25(x-2)^2$

Answer:

The correct option is A.

Step-by-step explanation:

If a line passes through two points $(x_1,y_1)$ and $(x_2,y_2)$ , then the equation of line is

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

Let y be the profit (in millions) after x years.

From the given graph it is clear that the line passes through the point (1,-100).

The company paid for these costs and made combined profits of $80 million after 4 years. It means the graph passes through the point (4,80).

The line passes through (1,-100) and (4,80). So, the equation of line is

$y-(-100)=\frac{80-(-100)}{4-1}(x-1)$

$y+100=\frac{180}{3}(x-1)$

$y+100=60(x-1)$

$y+100=60x-60$

Subtract 100 from both sides.

$y+100-100=60x-60-100$

$y=60x-160$

The function form is

$f(x)=60x-160$

Therefore, the correct option is A.
