Understanding Limits in Calculus

What does the term 'limit' refer to in calculus?

• The slope of a tangent line

• The y-value a function approaches

• The area under a curve

• The x-value a function approaches

In the parabola example, what is the limit as x approaches 1?

• 4

• 1

• 2

• 3

What happens to the graph at x = 0 in the first example of graph behaviors?

• It has a hole

• It is undefined

• It passes smoothly through

• It has a vertical asymptote

In the second graph behavior example, what is the y-value the function approaches from both sides?

• 0

• 1

• Undefined

• 2

Why does the limit not exist in the third example of graph behaviors?

• The function is continuous

• The function is not defined at x = 0

• The y-values approached from both sides are different

• The graph has a vertical asymptote

In the last example, what happens to the graph as x approaches 0 from the left?

• It increases without bound

• It approaches a y-value of 0

• It decreases without bound

• It remains constant

What is necessary for a limit to exist as x approaches a point?

• The y-values from both sides must approach the same value

• The function must be continuous

• The function must be defined at that point

• The x-values must be positive

What does it mean if a limit does not exist?

• The x-values are negative

• The function has a vertical asymptote

• The y-values from both sides do not match

• The function is not defined at that point

In the context of limits, what is meant by 'approaching a value'?

• Reaching the exact value

• Getting infinitely close to a value

• Staying constant at a value

• Moving away from a value

What is the significance of the y-value in determining limits?

• It determines the slope of the tangent

• It is the value the function approaches

• It indicates the function's continuity

• It shows the function's maximum
