CHAPTER 4 : BASIC DIFFERETIATION

Differentiate f(x) = 4x².

• 8x
• 16x
• 16x^2
• 8x^2

Find the derivative of:
f(x) = -5/x⁴

• -20/x⁵
• 20/x⁵
• -20/x³
• 20/x³

Find the derivative of:
f(x) = 2x² - 7x + 9

• 4x
• 4x + 7
• 4x - 7
• 9

What rule should be used in deriving h(x) = 2(x - 4)³

• Power rule

• Product rule

• Quotient rule

• General Power Rule

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
