STAAR REVIEW: Key Attributes & Functions DAY 5

Front

What is an x-intercept?

Back

The x-intercept is the point where a graph crosses the x-axis, meaning the value of y is zero at that point.

Front

What is a y-intercept?

Back

The y-intercept is the point where a graph crosses the y-axis, meaning the value of x is zero at that point.

Front

How do you find the x-intercept of a linear equation?

Back

To find the x-intercept, set y to 0 in the equation and solve for x.

Front

How do you find the y-intercept of a linear equation?

Back

To find the y-intercept, set x to 0 in the equation and solve for y.

Front

What is an asymptote?

Back

An asymptote is a line that a graph approaches but never touches or crosses.

Front

What is the horizontal asymptote of the function y = 2^x?

Back

The horizontal asymptote is y = 0.

Front

What does it mean for a function to be quadratic?

Back

A quadratic function is a polynomial function of degree 2, typically in the form f(x) = ax^2 + bx + c.

Front

What is the vertex of a quadratic function?

Back

The vertex is the highest or lowest point on the graph of a quadratic function.

Front

How do you evaluate a function at a specific point?

Back

To evaluate a function g(x) at a point, substitute the value of x into the function and simplify.

Front

What is the solution to g(x) = 4x - 7 when x = -9?

Back

g(-9) = 4(-9) - 7 = -36 - 7 = -43.
