Let f be defined as shown. What is f^-1(8)?

Mathematics

Gnoma [55]4 years ago
4 0

Answer:

From the picture when the input of f(x) is 6 the output is 8

So it's just the reverse f^-1(8) when the input is 8 the output is 6

So f^-1(8) = 6

Hope this helps you

Given the point (10, 25) and m = 2.5 , write the equation for the function m(t) point-stope form.
dalvyx [7]

Answer:

the equation for the function m(t) point-stope form will be:

  • y - 25 = 2.5 (x - 10)

Hence, option D is correct.

The graph is attached below.

Step-by-step explanation:

Given

Point (10, 25)

Slope m = 2.5

To determine

Write the equation for the function m(t) point-stope form.

We know that the point-slope form of the line equation is

y-y_1=m\left(x-x_1\right)

where

  • m is the slope of the line
  • (x₁, y₁) is the point

In our case:

  • m = 2.5
  • (x₁, y₁) = (10, 25)

so

substituting the values m = 2.5 and the point (10, 25) in the equation

y-y_1=m\left(x-x_1\right)

y - 25 = 2.5 (x - 10)

Therefore, the equation for the function m(t) point-stope form will be:

  • y - 25 = 2.5 (x - 10)

Hence, option D is correct.

The graph is attached below.
