Answer:

f(x) = 10x - 2x + 4.

Step-by-step explanation:

This is linear because the degree of x is 1.

The others have degree 2 , degree 3 and degree -1.

(f(x) = 2/x = 2x^-1)).

Not too sure about this one

Answer:

see explanation

Step-by-step explanation:

let y = f(x), then

y = 11x - 1

Interchange x and y and solve for y

x = 11y - 1 ( add 1 to both sides )

x + 1 = 11y ( divide both sides by 11 )

y = $\frac{x+1}{11}$ , hence

$f^{-1}$ (x) = $\frac{x+1}{11}$

What is an<br> Answer:<br> equation of the line that passes through the points (-2, 7) and (-8, 4)?

Mariana [72]

-2=x1 7=y1 -8=x2 4=y2

Y=Mx+b

Y2-y1 = 4-7 =-3
X2-x1 = -8-(-2) = -6
M (slope) = 3

Use the coordinate (-8, 4)

Y = MX + B = 4 = 3(-8) + b
4 = -24+ B
Add 24 to both sides to keep your equation balanced
B equals 28

Y = 3X + 28
