I'm bad at math, so the equation n+2n is 4n to me

F(x) look at the slope

[Emily Trebour @trebourmath]

When f(x) has a slope of 0, the graph f'(x) will have a y-value of zero.

[Caroline @caroline_math]

the derivative of F prime (x) won't exist at sharp peaks or valleys in F(x)!

[Irfan Nalic @Irfan_Stabmath]

derivative of a function is an expression which tells us the slope of a tangent line to the curve at any instant.

[Marcus Stamp @StampMitchell]

If f(x) has a cubic shape then f'(x) has a parabolic shape

[Claire Longo @claireSTABmath]

when drawing a f(x) graph from the derivative, it doesn't matter if it is drawn above or below the deriv just make sure the slope is right!

[Kenzie White @kwhiteIM4]

If you are given f(x) there is only one option for f prime (x)!!!

[Ann --- MATH @annMATH4]

F prime look at the y cord

[Brianna - MATH @brianna_math]

if f(x) is parabola then f'(x) is a line

[Emma Krall @emmalovesmath17]

Focus on the slopes with f(x)!!!!! Only worry about the y co's of f'(x) !! Don't get it twisted:))

[Kenzie White @kwhiteIM4]

Remember when finding an exact point for the equation of a line plug the number into the original equation and not the derivative!!!

[Ann --- MATH @annMATH4]

Always be sure to find a common denominator when adding or subtracting fractions!

[Emma Krall @emmalovesmath17]

Hey guys, don't worry about this quiz tomorrow! remember the equation, and use point slope form to find the tan line, & we'll be fine!

[Emma Krall @emmalovesmath17]

BREAKING NEWS: it's okay to have a radical in the denominator only if it's a function!!!!!!!

[Emma Krall @emmalovesmath17]

Once you plug everything into your definition of a derivative, it's just a simple limits problem :) we got it guys!

[Kenzie White @kwhiteIM4]

Helpful hint: make sure to only foil the part of the fraction you used the conjugate of and not both the numerator/denominator!!

[Caroline @caroline_math]

A secant line touches the graph at two points, while a tangent line touches the graph at one #themoreyouknow

[Emma Krall @emmalovesmath17]

When subtracting f(x) from f(x+h), remember to subtract the whole function, not just the first term :)

[Lara maluf @laraIM4]

f'(x) means the derivitve and is read " f prime of x"

[Ann --- MATH @annMATH4]

Use a secant line to estimate the instantaneous rate of change
