## sha0403 2 years ago help me to sketch this graph of f(x)=4x^2 and g(x)=x^3 i have a little confusing bcoz the question ask to find area.. but i don't know the shape of graph..

1. Mathmuse

area can be found through integration. You don't necessarily need to sketch unless the question asks you to do so specifically.

2. sha0403

oh but i don't understand if i don't know the shape of graph..

3. Mathmuse

Is the question to find the area between those two functions?

4. sha0403

yes..it want area between the function..

5. Mathmuse

f(x) is a parabola that is stretched by a factor of four.|dw:1356373670620:dw|

6. Mathmuse

g(x) is a cubic|dw:1356373761763:dw| the parabola is your upper function

7. sha0403

oo ok i see.. i just confuse abt the parabola..but now i know.. btw thank u very much.. ;)

8. Mathmuse

setting the equations equal to each other will allow you to find your bounds...if your not sure of the upper function, guess. if wrong you'll get a negative answer and you just have to change the sign

in area never have negative sign right? ok2 tq ya..
