if f(x) = 2(x − 5), find f(8).
4
6
8
16

f(8) = 6

Step-by-step explanation:

Given function is:

In order to find the value of a function on a particular input, the variable in the function is replaced with the value.

We have to find f(8), so putting 8 in place of x

So the value of function at 8 is 6 ..

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
