[@kingklaus2115]

@@ninjapirate123 Oh alright I wasn’t sure. Yeah there are some pretty bad teachers out there. I think the main problem comes down to how funding works. Schools should not be funded based on property taxes since it is impossible for students to grow out of low income areas with the low grade schools they have supplied. It creates an endless cycle of people going to public schools, failing out, and moving into dead end jobs where they start families and have kids that go right through the same process. Countries should spend less on defense and more on infrastructure, otherwise we are all going to suffer in the long run.

Put different values of x in the equation {Say, for example, f(x)=x^2}, note down the corresponding values for f(x). Mark these values of x and their corresponding values for f(x) on the co-ordinate axis. P.S: Take f(x) as your vertical axis and x as the horizontal axis.

[@FadilAidid]

yes the second interval where the function concave down supposed to be (-1,2), because the second derivative on the interval (-1,2) is negative (meaning the rate of the first derivative function on interval (-1,2) is decreasing). I think he just did a typo.. CMIIW

Can someone tell me how to plot graph of f' when graph of f is given but not the value of f

[@staycalm9979]

That is exactly what he teaches us at 7th minute in this video. Notice that there is no value given for the f(x) but still he manages to plot f'(x). Important point here is, slope of the original function f(x) is the Y-value for the derivative function. It doesn't have to be an exact graph like on computer. It is just an approximate graph. Examiners will not expect you to draw an exact graph. Imprint that point in your mind.
