I need help once again cause I'm stupid

[DreamLogic]

again its cause i wasn't paying attention but our math class tends to move slow so idrk how we moved this far ahead.
Its explicit equations for 2 exponential curves...



explicit equations

 

[Peek]

i have a good tip for u:





















listen in class

 

[Bellasprout]

F(x)=4x+1
g(x)=3^x

 

[FakeSham]

get good

 

[DreamLogic]

F(x)=4x+1
g(x)=3^x

oh, ty! if you can can you explain it so I actually know how to do it?

F(x) is easy, the equation of a linear function is y= mc+b, m being the slope, and b being the y intercept. The slope can be found using rise/run, which in this case is 4 up for every 1 right, meaning the slope is 4, and the y intercept is 1. Making the equation 4x+1.

g(x) is also easy if you know parent functions, you would know that is an exponential function (a^x)You can see by the given point that it goes through 2,9, meaning that a^2=9, which means a=3. The function has normal y intercept (that being 1) meaning nothing else needs to be added to the equation. So the equation is simply 3^x.

thank you so much!
