@marthaspirit18 ( lx-1l+1 x< or = 1
f(x)= ( lx-1l +3 x> 3

[Sierra Smith @SierraMath1]

@marthaspirit18 1. Factor the top and the bottom
2. cross out any things that are the same in the denomin and num
3. Fill out the rest of the parts you need to find according to what you have left

[Sierra Smith @SierraMath1]

@mtopchyanmath Yes DNE= Does Not Exist, which can be used when evaluating limits

[Sierra Smith @SierraMath1]

How to you prove that two functions are inverses of each other.

[Sierra Smith @SierraMath1]

When rationalizing fractions how do you know what things to cancel out?

[Sierra Smith @SierraMath1]

@STAB_MATH Both=8 !!!!!!

[Sierra Smith @SierraMath1]

@STAB_MATH E^x & ln(x) will both work

[Sierra Smith @SierraMath1]

What is the equation of this function?

[Sierra Smith @SierraMath1]

Sos!

[Sierra Smith @SierraMath1]

@STAB_MATH A function can't have two x's and y's therefore it wouldn't pass the vertical line test and this baby only has 1 of each

[Sierra Smith @SierraMath1]

@STAB_MATH I'm sure the man knows how to do the vertical line test!!

[Sierra Smith @SierraMath1]

Whn you have a Function like: y=4(x-3)(x+2) should you distribute the 4 before graphing it so that you can find the B & A to find the vertex

[Sierra Smith @SierraMath1]

In a Peicewise Function can both X's be equal too?

[Sierra Smith @SierraMath1]

@STAB_MATH X has to be factored out b4 it can be cancelled out of the top and bottom of the fraction

[Sierra Smith @SierraMath1]

@STAB_MATH The domain would be all real numbers b/c anything input gives an answer therefore range is 0 which also makes it infinity.
