Features (for this graph): • the domain is all Real numbers. These graphs increase rapidly in the \ (y\) direction and will never fall below the \ (x\)-axis. For "a" and "d", however, we're going to have to solve for these algebraically, as we can't determine them from the exponential function graph itself. Graph the inverse function. However, for each unit increase in t, t, 2 2 units are added to the value of L(t), L ( t), whereas the value of E(t) E ( t) is multiplied by 2. View 29. State the domain, range, and asymptote. This shows the selected domain that is graphed in other images. While horizontal and vertical shifts involve adding constants to the input or to the function itself, a stretch or compression occurs when we multiply the parent function [latex]f\left(x\right)={b}^{x}[/latex] by a constant [latex]|a|>0[/latex]. Since we want to reflect the parent function [latex]f\left(x\right)={\left(\frac{1}{4}\right)}^{x}[/latex] about the x-axis, we multiply [latex]f\left(x\right)[/latex] by –1 to get, [latex]g\left(x\right)=-{\left(\frac{1}{4}\right)}^{x}[/latex].

For a window, use the values –3 to 3 for x and –5 to 55 for y. Since [latex]b=\frac{1}{2}[/latex] is between zero and one, the left tail of the graph will increase without bound as, reflects the parent function [latex]f\left(x\right)={b}^{x}[/latex] about the, has a range of [latex]\left(-\infty ,0\right)[/latex]. Exponential functions are used to model relationships with exponential growth or decay. This lesson involves investigating how the graph of an exponential function changes when 0 < b <1, b = 1, or b >1.
