Graphing by Hand

[tlg_steps style=”steps-style-2″][tlg_steps_content step_link=”url:http%3A%2F%2F127.0.0.1%2Fmkmath%2Fcalculus%2F” title=”Calculus” icon=”ti-arrow-circle-right” subtitle=”Topics”][tlg_steps_content step_link=”url:http%3A%2F%2F127.0.0.1%2Fmkmath%2Fcalculus%2Fintro%2F|title:Introductory%20Calculus” title=”General” icon=”ti-arrow-circle-right” subtitle=”Topics”][/tlg_steps] Here are tips for graphing. First, you need to find x-intercepts and y-intercept, if possible. For x-intercepts, setting y=0 to find x-values and similarly, setting x=0 to find y-intercept. Then, investigate if there are any asymptotes for fractional functions. For the horizontal asymptotes, we need…
