Intro to Equations of Exponential Functions

Which is the correct standard form equation of an exponential function?

• $y=mx+b$

• $y=b+mx$

• $ax+by=c$

• $y=a\left(b\right)^x$

Pick the only TRUE statement about

 $y=ab^x$  

• x is the independent variable, y is the dependent variable

• x is the dependent variable, y in the independent variable

• a is the growth factor

• b is the starting value

Choose the correct equation for an exponential function that starts at 5 and has a growth factor of 2

• $y=2\left(5\right)^x$

• $y=5\left(2\right)^x$

• $y=a\left(2\right)^5$

• $y=2a^5$

Choose the correct equation for an exponential function that has a growth factor of 3 and starts at 1

•  $y=a\left(1\right)^3$ 

•  $y=3\left(a\right)^1$ 

•  $y=3\left(1\right)^x$ 

•  $y=1\left(3\right)^x$ 

Choose the correct equation for the table

• $y=1\left(10\right)^x$

• $y=10\left(1\right)^x$

• $y=1\left(1\right)^x$

• $y=10\left(10\right)^x$

Choose the correct equation for the table

• $y=4\left(5\right)^x$

• $y=5\left(20\right)^x$

• $y=5\left(4\right)^x$

• $y=5\left(15\right)^x$

Oscar's mom agrees to a unique allowance plan for 2021. Oscar starts with $3 in January and his mom promises to double it each month. Choose the correct equation:

• $y=1\left(3\right)^x$

• $y=3\left(2\right)^x$

• $y=3\left(1\right)^x$

• $y=2\left(3\right)^x$

Pick the correct statement for the equation

 $y=6\left(3\right)^x$  

• 6 is the growth factor and 3 is the starting value
