Fill the blanks with $(-\infty,\infty) ... (0,\infty)$

Work Step by Step

The graph of $ y=b^{x}$ when $ b \gt 1$ - is above the x-axis, - always rises, - approaches $ y=0$ on the far left, - rises to pass through ($0,1$) on the y axis, - continues to rise rapidly, passing through ($1,b $), ($2,b^{2})$,... Domain: all reals, $(-\infty,\infty)$ Range: $(0,\infty)$ Thus, we fill the blanks with: $(-\infty,\infty) ... (0,\infty)$
