Find a formula for the exponential function passing through the points 4
3,
and (1,20)
125
f(x) -

Step-by-step explanation:

Given

Required

Determine the exponential equation

An exponential equation is of the form:

In:

---- (1)

In:

--- (2)

Divide (1) by (2)

Take 4th roots of both sides

Substitute in

Solve for a

Hence, the equation is:

536

step-by-step explanation:

we can't see all full 4 options, but if this is the full option, than the very left one is correct:

-2/5 * -3 3/4

remake the question, adding a picture of all the question, or write down the full left and right answers.
