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