What is the ZERO of a function?

Back

The zero of a function is the value of x that makes the function equal to zero. For example, if f(x) = x - 2, the zero is x = 2.

Who is Scooby Doo?

Back

Scooby Doo is a fictional dog and the main character in the animated television series 'Scooby-Doo, Where Are You!'. He is known for solving mysteries with his friends.

Front

What is the y-intercept of a graph?

Back

The y-intercept is the point where the graph of a function crosses the y-axis. It is represented as (0, y). For example, if the y-intercept is (0, 7), the graph crosses the y-axis at 7.

Front

What is slope-intercept form?

Back

Slope-intercept form is a way of writing the equation of a line as y = mx + b, where m is the slope and b is the y-intercept.

Front

Who is Sonic?

Back

Sonic is a fictional character and the main protagonist of the 'Sonic the Hedgehog' video game series. He is known for his speed and adventurous spirit.

Front

How do you find the zero of a linear function?

Back

To find the zero of a linear function, set the function equal to zero and solve for x. For example, for f(x) = 2x - 4, set 2x - 4 = 0, which gives x = 2.

Front

What does the y-intercept (0, 7) indicate?

Back

The y-intercept (0, 7) indicates that when x = 0, the value of y is 7. This is the point where the line crosses the y-axis.

Front

What is the significance of the slope in a linear equation?

Back

The slope indicates the steepness of the line and the direction it goes. A positive slope means the line rises, while a negative slope means it falls.

Front

What is the equation of a line with a slope of -2 and a y-intercept of 5?

Back

The equation of the line is y = -2x + 5.

Front

What is a function?

Back

A function is a relation that assigns exactly one output for each input. For example, f(x) = x^2 is a function.
