Answer:

Step-by-step explanation:

We find the ratio by dividing two y-values from 2 consecutive x values (1 unit apart). Notice that in the table, all x-values are 1 unit apart. We can choose any pair of consecutive points.

Let's choose: (2,-4) and (1,-2). We divide -4/-2=+2.

Answer:

HERE IS YOUR ANSWER

Step-by-step explanation:

Use the mirror equation:

1/di + 1/do = 1/f

where di = -10 cm and f = +15 cm. (Note that di is negative if the image is virtual.)

Substitute and solve for do.

1/do + 1/(-10 cm) = 1/(15 cm)

1/do = 1/(15 cm) - 1/(-10 cm) = 5/(30 cm)

do = 6 cm

Hope it helps you

Answer:

2/3

Step-by-step explanation:

so the inverse takes us from the range to the domain... they tell us that f(4) goes to 5.. so if we were to take the inverse f $\left \[-1} \atop$ (5) it takes us back to 4... and the slope at 4 or the derivative was 2/3 so that's what we get for f $\left \ {{-1} \atop$ '(5) :)
