Step-by-step explanation:

An easy-ish way to graph something in slope-intercept form is to use the y-intercept and the slope because that info is given.

the y -int is when x = 0 and then y would equal -1/2. (0,-1/2)

then the slope is 3/4 which is rise over run so go three up (rise) and 4 across (run). make sure that your line has a positive slope ( / ) because the slope is positive in the equation, not negative ( \ )

You now have 2 points. Draw a line connecting the two points.

Use the site called Desmos, it's a graphing calculator and should help you in all the ways you need. It isn't complex. Just put that equation in a box and it graphs it for you.

What is the inverse of the function g(x)=x^3/8+16

shtirl [24]

Answer:

The inverse of the function is $f^{-1}(x) = \sqrt[3]{\frac{x-16}{8}}$

Step-by-step explanation:

Inverse of a function:

Suppose we have a function y = g(x). To find the inverse, we exchange the values of x and y, and then isolate y.

In this question:

$y = \frac{x^3}{8} + 16$

Exchanging x and y:

$x = \frac{y^3}{8} + 16$

$\frac{y^3}{8} = x - 16$

$y^3 = \frac{x-16}{8}$

$y = \sqrt[3]{\frac{x-16}{8}}$

The inverse of the function is $f^{-1}(x) = \sqrt[3]{\frac{x-16}{8}}$

What is the area of the figure?

RUDIKE [14]

The area formula for rectangles is lxw. To solve, I would divide the figure up into 3 rectangles- top,middle and bottom, then find the areas and add them together.

Top: 4x13=52 cm^2
Middle: 5x8=40 cm^2
Bottom: 21x10=210 cm^2

(5 is the width of the middle piece. You get it from subtracting. 21-8-8=5. 13 is the width of the top piece. 5+8=13)

52+40+210
=302 cm^2
So your answer is 302 square centimetres.
