Without a precise definition of k, we cannot answer the question. Some exponential functions have the form

f(x) = Ab^{kx}

where A, b, and k are constants. Could this be what they are asking for in your assignment? If so, then k is the coefficient in front of x in the exponential function.

Examples:

f(x) = 5 (2)^{3x }⇒ k = 3

g(x) = 10 (5)^{x/7 }⇒ k = 1/7

Regarding finding y-intercept, the y-intercept is always the value of the function at x = 0.

wait in my notes, it says k is transformation of the graph.. what does this mean? and it also says what it approaches!02/07/20
