• only 2
• only 1
• until you can no longer derive it

Find the slope of the tangent line to f(x) = -3x²-6x at x = 1.

• m = 0
• f'(x) = -6x - 6
• f'(x) = 6x
• m = -12

If a function has a derivative that is negative, what does that tell you?

• The function is increasing
• The function is decreasing

The three situations where derivatives fail to exist are at corners or cusps, at a vertical tangent, and...

• horizontial tangent
• discontinuity
• curve
• intercepts

Differentiate f(x) = (9 - 4x²)^-1

• 8x/(9 - 4x²)^-2

• 8x/(9 - 4x²)²

• -8x/(9 - 4x²)^-2

• -8x(9 - 4x²)²

When do you use the chain rule?

• anytime you want
• when there is a function in a function
• where there are multiple layers to a lasagna (yum)
• when there is division
