Use the definition of the derivative (aka the limit process) to find the derivative of y=x^2+9 (be ready to show work on the test).

• x^2

• 2x+9

• 2

• 2x

This is NOT a correct notation for a derivative

• y ' (say it as "y prime")

• f '(x) (say it as "f prime of x")

• dy/dx

• dx/dy

Use the definition of the derivative (aka the limit process) to find the derivative of y=x^2-2x+3 (be ready to show work on the test).

• y ' = 2x - 2

• y ' = 2x^2

• y ' = 2x

• y ' = x^2

Write the slope of the line tangent to the graph of y=x^2-2 at the point x = 8.

• 2

• -4

• -8
