Evaluating Functions with Desmos

What does the number inside the parentheses in function notation represent?

• The function output

• The function input

• The function name

• The function type

Why can evaluating functions with negative numbers be challenging by hand?

• Negative numbers are not allowed in functions

• Calculators cannot handle negative numbers

• It is impossible to evaluate negative numbers

• It requires a lot of parentheses which can lead to mistakes

What is the value of f(2) if f(x) = x^3 + 9?

• 21

• 19

• 17

• 11

Which of the following is a correct way to evaluate a function in Desmos?

• Type the function on one line and the value on another line

• Type the function and the value on the same line

• Type only the value

• Type only the function

If G(x) = 10x + 8, what is G(8)?

• 78

• 80

• 88

• 90

What is the value of 4F(2) - G(2) if F(x) = x + 7 and G(x) = 7x?

• 24

• 22

• 20

• 18

Why is using Desmos advantageous for evaluating multiple functions at once?

• It can only evaluate one function at a time

• It eliminates the need for a calculator

• It saves time and reduces arithmetic errors

• It provides step-by-step solutions

What should you do if you encounter a longer problem involving multiple functions?

• Use Desmos to evaluate each function separately

• Use a different calculator

• Solve it by hand to avoid mistakes

• Skip the problem
