Explain exponential functions Share with your friends Share 0 Aarushi Mishra answered this Exponential function is defined asf:ℝ→ℝ+fx=ax, where a>0 and a≠1. 'a' is a constant and a∈ℝE.g y=2x, y=10x, etcThe text actually says thatConsider an example fx=81xf14=8114Now 8114 can take many values like 3, 3i, -3i, -3 But since co-domain of function is positive real numbers so, we will only consider positive real values i.e. 3 here f14=8114=3If a=1, then no matter what is the value of x, fx=1 0 View Full Answer
