Function k is a linear function with a slope of 1/2 that passes through the point (4,2). What equation represents Function K?

Novay_Z [31]

Answer:

A. y = 1/2 x.

Step-by-step explanation:

Use the point-slope form of a linear (straight line) function:

y - y1 = m(x - x1)

m = 1/2, x1 = 4 and y1 = 2, so:

y - 2 = 1/2(x - 4)

y = 1/2x - 2 + 2

y = 1/2 x (answer)

Find the inverse function of h(x) = -2/3x + 6.

nalin [4]

Answer:

$h^{-1}(x)=-\frac{3}{2}x+9$

Step-by-step explanation:

To find inverse of a function, follow the steps below:

1. replace h(x) with y

2. Interchange x and y

3. Solve for the new y

4. Replace y to $h^{-1}(x)$ (this is the inverse function)

Step 1: y = -2/3x+6

Step 2: x = -2/3y+6

Step 3:

$x=-\frac{2}{3}y+6\\\frac{2}{3}y=-x+6\\y=\frac{-x}{\frac{2}{3}}+\frac{6}{\frac{2}{3}}\\y=-\frac{3}{2}x+9$

Step 4:

$y=-\frac{3}{2}x+9\\h^{-1}(x)=-\frac{3}{2}x+9$

This is the inverse function.
