Which of the following is the inverse of y=3* ?<br> E OF<br> y=log,<br> y = logix
Rufina [12.5K]

Answer:

y =  log_{3}(x)

Step-by-step explanation:

The given function is

y =  {3}^{x}

To find the inverse, we interchange x and y to get:

x =  {3}^{y}

We now solve for y by taking antilogarithm.

y =  log_{3}(x)

Therefore the inverse of the given exponential equation is the logarithm function

y =  log_{3}(x)

Can someone plz help I don’t under sand and I will get a F if I don’t turn this in tmr
Digiron [165]

Answer:

Mile Run = 12.85  Long Jump = 6.63  Softball Toss = 22.1

Step-by-step explanation:

To do this you do not just plug it in. If you read it carefully, you would have to add. For example, Brianne  would run 2.36 minutes faster than Crystal, so that would be 10.49 + 2.36 = 12.85. There you go! Hope this helps!
