The values that define the viewing window can be set manually under WINDOW or by using the ZOOM key. The boundaries of a viewing window are xmin: the smallest value on the x-axis (the left boundary of the window) ymin: the smallest value on the y-axis (the bottom boundary of the window) xmax: the largest value on the x-axis (the right boundary of the window) ymax: the largest value on the y-axis (the top boundary of the window) xscl: the distance between ticks on the x-axis (helps visually find x-intercepts and other points) yscl: the distance between ticks on the y-axis (helps visually find the y-intercept and other points) * Parentheses should be placed around numerators and/or denominators of fractions, fractions that are multiplied by a variable, exponents consisting of more than one symbol, and in other places where the order of operations needs to be indicated.
