Transforming Exponential Functions

What is the parent function that we use to compare exponential functions?

• $y=x$

• $y=2^x$

• $y=x^3$

• $y=0$

When the number multiplied in front is greater than 1, the graph becomes...

• backwards

• upside down

• more steep

• less steep

When the number multiplied in front is less than 1, the graph becomes...

• backwards

• upside down

• more steep

• less steep

When we make the function negative, the graph does what?

• flips

• turns right

• turns left

• moves up

When we add a number in the parentheses (in the exponent), what happens?

• Shifts up

• Shifts down

• Shifts left

• Shifts right

When we subtract a number in the parentheses (in the exponent), what happens?

• Shifts up

• Shifts down

• Shifts left

• Shifts right

If you add a number at the end, what happens?

• Shifts up

• Shifts down

• Shifts left

• Shifts right

If you subtract a number at the end, what happens?

• Shifts up

• Shifts down

• Shifts left

• Shifts right

Which of these is an exponential function?

• 
• 
• 
• 

Would this function represent exponential growth or decay?

 $y=\left(0.4\right)^x$  

• Exponential growth

• Exponential decay

• Both

• Neither
