Review Day 3

Front

Given g(x) = 4x - 7, find g(-9).

Back

g(-9) = -43

Front

Given f(x) = -4x - 10 and f(x) = 10. Find x.

Back

x = -5

Front

Solve by elimination: 4x + 9y = 28 and -4x - y = -28.

Back

(7, 0)

Front

All of the y values or outputs are called what?

Back

Range

Front

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain and range.

Back

D: {-4, 0, 1, 2}, R: {-4, -3, 1}

Front

What is the definition of a function?

Back

A relation where each input has exactly one output.

Front

What is the domain of a function?

Back

The set of all possible input values (x-values).

Front

What is the range of a function?

Back

The set of all possible output values (y-values).

Front

What does it mean to solve by elimination?

Back

A method to solve a system of equations by eliminating one variable.

Front

What is the slope-intercept form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.
