Intro to Derivatives

The slope of the tangent line is...

• the slope of the normal line
• the original graph
• the reciprocal of the graph of f(x)
• the derivative

Is differentiating the same as taking the derivative?

• yes

• no

• sometimes

At which point(s) will the slope(s) of the tangent line be POSITIVE?

• at C only

• at points A, C and E only

• at point B and D only

• at points A and E only

At which point(s) will the slopes of the tangent line be zero?

• at C only

• at points A, C and E only

• at point B and D only

• at points A and E only

• 0

Find the derivative of the given equation

f(x)=12-8x

• -8x

• -8s

• -8

• 12 - 8

Find the derivative of the given equation
f(x) = 1 - x²
