How do I find the x & y intercept of a equation with exponents?

[Evan_aa]

I have no idea how to do number #29!!! It doesn't even look like a linear equation to me. Please tell me where to at least start. Thankx you

The x intercept is the point (or points) on a curve where y is zero. That's all. The y intercept is the point (or points) where x is zero. For #29, when y is zero you have 0 = 2x^3 - 4x^2 = x^2(x - 4). This curve has two x intercepts. You can probably do the rest now.

This is all pretty pointless in my opinion. Not algebra, which is a useful way to solve problems, but all the stupid vocabulary that mostly real mathematicians don't use, like "x-intercept". I did graduate work in math. Don't think I ever said "x-intercept" after high school.

Here's what real mathematicians call an x-intercept: https://en.wikipedia.org/wiki/Zero_of_a_function

Man my math teacher would be so disappointed that the easy stuff we did I already forgot.
But yea it's not linear.

The stuff we did years ago...

29 is indeed not a linear equation since it has the 3 above the 2x.

x-intercept, set up to zero.
0= 2x (3) - 4x (2)
x-intercept= (0,0), (2,0)

Y-intercept, replace X with 0
y= 0 - 0
y-intercept= (0,0)

So the X and y intercepts are (2,0)

if u can't solve the problem dont worry.. they won't become very useful in the future anyway haha

Notice how no girls responded to this. Girls hate math.

[pinkzoesbb]

I love math!

[Evan_aa]

Yea I do hate math 😂😂😂

Hope it helps!
best of luck😊

Been years since I've done any of this math but always reduce math to its most basics to solve it. So what is 2x3 - 4x2... 2*x*x*x - 4*x*x... can you solve it now?

[Kayyumshaikh786]

To find y intercept, put x=0 and for x intercept put y=0 and solve equation simultaneus until coordinates obtain. Thnx for asking.

This is really easy. I can't believe this can be difficult for someone who is 18 years old.

[azsxdc1234]

there are multiple ways to do it, the easiest is with derivatives.

[alexald]

replace for each of the variables with 0 to get the other ones intercept... easy

[akadatank44]

Punch it into a graphing calculator.

[Partywithtom]

Generally one would use math.

hope this helps!

sorry I forgot all this over the summer

what is the answer by the way

2x^3=2x^2×2x^2
