What is a common mistake students make when drawing log graphs?

• Using incorrect scales

• Using only one color

• Drawing straight lines

• Ignoring the x-axis

What is the significance of the y-intercept in a log graph?

• It is always zero

• It is the point where the graph crosses the y-axis

• It is irrelevant to the graph

• It is the maximum value of the graph

What is the first step in calculating the area under a curve?

• Calculating the slope

• Forming an integral

• Drawing the curve

• Finding the x-intercept

What happens if you integrate backwards?

• You get an undefined result

• You get zero

• You get a negative number

• You get a positive number

How are logarithms and exponentials related?

• They are unrelated

• They are inverse operations

• They are both linear functions

• They are both quadratic functions

What is the purpose of comparing areas to the y-axis?

• To calculate the slope

• To find the x-intercept

• To avoid using integrals

• To simplify calculations

What is the area of a rectangle with width 1 and height 'e'?

• 1

• e

• e-1

• 2e

What is the value of 'e' approximately?

• 2.71

• 0.57

• 1.62

• 3.14

Why is 'e' considered an irrational number?

• It cannot be expressed as a simple fraction

• It is a whole number

• It is less than 1

• It is a negative number

How can irrational numbers be understood despite their complexity?

• By using them in simple calculations

• By ignoring them

• By approximating them

• By converting them to fractions
