🧐 Week 2 Quizizz | Inverse Functions and Function Operation 🧐

For the following problem, what operation will you use on the exponents?

• Multiply
• Add
• Subtract
• Nothing

Simplify:

• 25
• 125
• 625
• 1/5

When f(x) = 9 - 3x and g(x) = 5x - 7

find f(x) + g(x).

• 14x - 10

• -8x + 2

• 2x + 2

• 2x - 2

• 34

• 71

• 35

• 142

The inverse of the function f(x) is written as ...

• f ^-1(x)
• f ²(x)
• f '(x)
• f ⁺(x)

When finding the inverse of a relation, 
1st you replace f(x) with y
2nd switch the x's and y's
What do you do next?

• solve for y
• replace y with f^-1(x)
• solve for x
• find the greatest common factor

What is the FIRST step I need to take to solve for x in the following equation?

• Add 9 to both sides

• Take the square root of both sides

• Divide both sides by 49

• Multiply both sides by 9
