Evaluate a Function Plug in Expression

Find f(0)

• 7

• 8

• 9

• 10

Is this relation a function?

• yes; Because no x-values repeat

• no; because one or more x values repeat

Is this relation a function?

• yes; Because no x-values repeat

• no; because one or more x values repeat

Simplify.  Hint: Plug in a value on original expression and evaluate. Then plug in the same value you plugged in on original expression on answer choices and evaluate each to find matching outcome.

• (m+6)/(m-3)

• 7/(m-3)

• 7(m+6)

Simplify.  Hint: Plug in a value on original expression and evaluate. Then plug in the same value you plugged in on original expression on answer choices and evaluate each to find matching outcome.

• (x-9)/(x+9)

• 1/(x-9)

• (x+9)

Simplify.  Hint: Plug in a value on original expression and evaluate. Then plug in the same value you plugged in on original expression on answer choices and evaluate each to find matching outcome.

• 5x / 3

• 10x / (x - 8)

• 10x

Simplify.  Hint: Plug in a value on original expression and evaluate. Then plug in the same value you plugged in on original expression on answer choices and evaluate each to find matching outcome.

• (x + 9)

• (x - 3) / (x + 2)

• (x + 9) / (x + 2)

Simplify:rac{x^2+7x+10}{x^2-4} Hint: Plug in a value on original expression and evaluate. Then plug in the same value you plugged in on original expression on answer choices and evaluate each to find matching outcome.

Simplify.  Hint: Plug in a value on original expression and evaluate. Then plug in the same value you plugged in on original expression on answer choices and evaluate each to find matching outcome.

Simplify:rac{x^2-4x-45}{x^2-81} Hint: Plug in a value on original expression and evaluate. Then plug in the same value you plugged in on original expression on answer choices and evaluate each to find matching outcome.
