What is a function?

Back

A function is a relation that assigns exactly one output for each input. It can be represented as f(x) where x is the input.

Front

What does w(t) = 100 - 2t represent in a real-world scenario?

Back

It represents the amount of water left in a cup after t seconds, starting with 100 ml and losing 2 ml every second.

Front

How do you evaluate a function?

Back

To evaluate a function, substitute the given input value into the function's equation and simplify.

Front

What is the solution to f(x) = 3x - 9 when x = 5?

Back

f(5) = 6.

Front

What is the correct method to solve the equation 19 - 2k = 3k - 1?

Back

You should isolate k by moving all k terms to one side and constant terms to the other.

Front

What is the error in the equation 19 - 2k = 3k - 1?

Back

Instead of adding 3k, they should subtract 3k.

Front

What does it mean if an equation has no solution?

Back

It means that there are no values for the variable that can satisfy the equation.

Front

What is the first step in solving the equation 5d = 2d - 18?

Back

Subtract 2d from both sides to isolate the variable d.

Front

What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables that are solved together.

Front

How do you find the solution to a system of equations graphically?

Back

By plotting the equations on a graph and identifying the point(s) where they intersect.
