You can put this solution on YOUR website! Find an approximate equation y=ab^x of the exponential curve that contains the given points.
Round the values of a and or b to two decimal places if necessary.
(0,4)(3,79)
:
Replacing x and y with 0, 4
4 = ab^0
4 = a*1; (any term with a 0 exponent equals 1)
a = 4
:
replacing a, x, y with 4, 3, 79, find b
4*b^3 = 79
b^3 =
b = , find the cube root
b = 2.703
:
the equation for this curve: to two decimal places
looks like this:
