What is a zero of a function?

Back

A zero of a function is a value of x that makes the function equal to zero. It is the x-coordinate where the graph of the function intersects the x-axis.

Front

Evaluate f(x) = -2x + 13 for f(10).

Back

f(10) = -2(10) + 13 = -20 + 13 = -7.

Front

What is a function?

Back

A function is a relation that assigns exactly one output for each input. In ordered pairs, no two pairs can have the same first element.

Front

Simplify (6x^9y^5)^2.

Back

(6x^9y^5)^2 = 36x^{18}y^{10}.

Front

How do you find the y-intercept of a line given in standard form?

Back

To find the y-intercept, set x = 0 and solve for y.

Front

What is the y-intercept of the line 2x - 3y = 12?

Back

The y-intercept is (0, -4).

Front

What does it mean for a set of values to be a function?

Back

A set of values is a function if each input (x-value) corresponds to exactly one output (y-value).

Front

What is the process to evaluate a linear function?

Back

To evaluate a linear function, substitute the given x-value into the function's equation and solve for y.

Front

What is the standard form of a linear equation?

Back

The standard form of a linear equation is Ax + By = C, where A, B, and C are integers.

Front

What is the significance of the coefficients in a polynomial?

Back

The coefficients determine the shape and position of the graph of the polynomial function.
