Basic Derivative Information and Power Rule
At what values of a and b is f(x) differentiable.
a = -8
b = -5
Where is the function continuous but not differentiable.
x= -4 and x = 0
Find the equation of the tangent line of
y = x^4, x = -2
y - 16 = 32(x+2)
f(x)= tanx / x²+1, what is f′(x)?
f′(x)= [x2sec2x+sec2x - tan2x] / (x²+1)²
