Function Evaluation and Substitution Concepts

The video tutorial explains how to evaluate a function by substituting a given input into the equation. It starts with writing the equation with a placeholder, then substitutes the input value, and finally evaluates the expression to find the solution.

What is the first step in evaluating a function?

• Square the input

• Add a constant to the input

• Substitute the variable with the input

• Multiply the input by a constant

In the context of function evaluation, what does it mean to 'substitute'?

• Add a constant to the variable

• Multiply the variable by a constant

• Replace the variable with the given input

• Replace the variable with a blank

What is the purpose of writing the equation with a blank?

• To prepare for substitution

• To simplify the equation

• To add a constant

• To eliminate the variable

What is the next step after setting up the equation with a blank?

• Add a constant to the blank

• Multiply the blank by a constant

• Substitute the input into the blank

• Solve the equation

What operation is performed on the input after substitution?

• It is squared

• It is divided by a constant

• It is multiplied by a constant

• It is added to a constant

What is the result of squaring the input -10?

• 0

• -100

• 100

• 10

After squaring the input, what is the next step?

• Add a constant

• Subtract a constant

• Multiply by a coefficient

• Divide by a constant

What is the result of multiplying -12 by 100?

• 100

• -100

• 1200

• -1200

What is added to the product of -12 and 100?

• -1

• 1

• 0

• 10

What is the final result of evaluating the function with input -10?

• -1199

• 1199

• -1200

• 1200
