If f(x) = - 8x +2 then f^-1(x) =

mrs_skeptik [129]

Answer:

f^-1(x) = -1/8x +1/4

Step-by-step explanation:

To find the inverse of a function

Exchange x and y and then solve for y

y =-8x+2

Exchange x and y

x = -8y+2

Now solve for y

Subtract 2 from each side

x-2 = -8y+2-2

x-2 = -8y

Divide by -8

(x-2)/-8 = -8y/-8

Distribute

-1/8x +1/4 = y

f^-1(x) = -1/8x +1/4

Suppose line n has a slope of 5/7 and passes through (4,8). what is the equation for n in point-slope form?

Olegator [25]

Answer:

$\large\boxed{y-8=\dfrac{5}{7}(x-4)}$

Step-by-step explanation:

The point-slope form of an equation of a line:

$y-y_1=m(x-x_1)$

m - slope

We have the slope $m=\dfrac{5}{7}$ and the point $(4,\ 8)$ .

Substitute:

$y-8=\dfrac{5}{7}(x-4)$
