Question

Graph the function ƒ(x) = ∛x + 2.

Answer 1

Do you know how to find x intercept, y intercept?

Answer 2

No, I´m new to this

Answer 3

To find x-intercept, set f(x) = 0 and solve for x

Answer 4

\[0 = \sqrt[3]{x} + 2\]. Can you solve it?

Answer 5

No, does ^3 need to be squared?

Answer 6

\[-2 = \sqrt[3]{x}\]
\[(-2)^{3}= x\]
x= ?

Answer 7

cubed, not squared

Answer 8

-8

Answer 9

Am I correct?

Answer 10

Yes :) so x intercept = (-8,0)
Now to find y intercept set x= 0
f(x) = 0 + 2
f(x) = 2
y intercept at (0,2)

Answer 11

so the answer is x= (-8,0) and y= (0,2) ?

Answer 12

No now you need to know a few points,
find f(x) when x = -4,-2,-1,1,2,4

x y (aka f(x))
-3 0.5
-1 1
1 3
2 3,.2
3 3.4


Now that you have all these points, graph them and connect the dots.

Answer 13

not literally connect the dot but the draw the line, yknow what I mean :)

Answer 14

line/curve

Answer 15

-3=3? thats how i would match them?

Answer 16

remember (-8,0) and (0,2)

Answer 17

no, (-3,0.5) (-1,1) (1,3) (1,3) (2, 3.2) (3, 3.4)
These are points you'd put on the graph, then draw a curve/line through them.

Answer 18

Ok, are there some more steps or (-3,0.5) (-1,1) (1,3) (1,3) (2, 3.2) (3, 3.4) is the answer

Answer 19

I thought you have to graph it?
If you graph it then draw the line then that's the answer.

Answer 20

I do have to graph it but I'm new to this. Draw a line?

Answer 21

get your graphing paper out if you have some, or use line paper. Draw a big cross like this
