$A function with a graph that is symmetric about the origin is called an odd function. Note: A function can be neither even nor odd if it does not exhibit either symmetry. For example, \displaystyle f\left (x\right)= {2}^ {x} f (x) = 2x is neither even nor odd. Also, the only function that is both even and odd is the constant function .... Labelle perfume$

The function y = a x, a ≥ 0 is defined for all real numbers.Hence, the domain of the exponential function is the entire real line. The exponential function always results in a positive value. Thus, the range of the exponential function is of the form y= a x is {y ∈ ℝ: y > 0}. Therefore, Domain = ℝ, Range = (0, ∞)The first, which shows that the limit DOES exist, is if the graph has a hole in the line, with a point for that value of x on a different value of y. If this happens, then the limit exists, though it has a different value for the function than the value for the limit. Please click on the image for a better understanding.Solution. We see that the function is not constant on any interval. The function is increasing where it slants upward as we move to the right and decreasing where it slants downward as we move to the right. The function appears to be increasing from \displaystyle t=1 t = 1 to \displaystyle t=3 t = 3 and from \displaystyle t=4 t = 4 on.Here is a step-by-step guide to identify the function from the graph: Step 1: Foundational Grounding.
