Determine the maximum and minimum number of turning points for the function h(x) = -2x^4 - 8x^3 + 5x -6. Maximum:3 Minimum:1 Is this a valid reason: A quartic polynomial function has a 3 Turning points. The turning point is always 1 less than the degree. For example degree 4=3...

Determine the x-intercepts of the polynomial function y=-6(x+7)^4 + 5. Round to two decimal places, if necessary. y=-6(x+7)^4 + 5 0=-6(x+7)^4 + 5 -5=6(x+7)^4 -5/6 =(x+7)^4 There are no x-intercepts??

Got it! THank you~~~~~~~

Someone verify if this is correct, please! 1. Draw a distance versus time graph that corresponds to the walk described below. Adam starts 8 m away from the motion sensor and walks in a straight line toward the sensor at a constant rate of 0.5 m/s for 3 s. He immediately begins...

Ok, thanks~

Math
Btw, may I post another question here with image, I just want you to verify if I am correct :|

Math
So I am right? =D

I can't post exact link due to errors :S

Here is the link imgur dot com/3V1AX The question asks: A distance versus time graph is shown below. What is the instantaneous rate of change in the distance at t=6s sorry, it won't rotate, you can save the pic and rotate >.<
