Function Notation and Zeros of Functions

What is the significance of zeros of a function in graphical representation?

• Zeros of a function indicate the y-intercepts of the graph.

• Zeros of a function have no significance in graphical representation.

• Zeros of a function indicate the x-intercepts of the graph.

• Zeros of a function represent the maximum points on the graph.

Explain the process of finding zeros of a function graphically.

• We look for the x-intercepts or the points where the graph crosses the x-axis.

• We count the number of peaks and valleys on the graph.

• We look for the y-intercepts or the points where the graph crosses the y-axis.

• We find the average value of the function over the given interval.

How do you determine the number of zeros of a function from its graphical representation?

• By counting the number of times the graph crosses the x-axis.

• By counting the number of times the graph crosses the y-axis.

• By calculating the area under the curve.

• By determining the slope of the function at different points.

What are the different methods to find the zeros of a function?

• Factoring, quadratic formula, completing the square, graph of the function

• Using a protractor

• Guessing and checking

• Asking a friend for the answer
