Algebra 1 Midterm Review

Front

What is the domain of the function {(0,1), (1,-3), (2,-4), (-4,1)}?

Back

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

Front

What is the range of the function {(0,1), (1,-3), (2,-4), (-4,1)}?

Back

R: {-4, -3, 1}

Front

How do you solve for t in the equation D = rt?

Back

t = D/r

Front

What is the solution to the system of equations that results in (-3,-8)?

Back

(-3,-8)

Front

Is the relation {(11,2), (11,3)} a function? Why?

Back

No, because the x-value 11 has two y-values pair with it.

Front

What are the steps to solve the equation 5b - 6 = 24?

Back

Add 6 to both sides and divide both sides by 5.

Front

What is a function?

Back

A relation where each input (x-value) has exactly one output (y-value).

Front

What is the difference between domain and range?

Back

Domain is the set of all possible input values (x-values), while range is the set of all possible output values (y-values).

Front

How do you determine if a relation is a function using a graph?

Back

Use the vertical line test: if a vertical line intersects the graph at more than one point, it is not a function.

Front

What does it mean to solve a system of equations?

Back

Finding the values of the variables that satisfy all equations in the system simultaneously.
