okay so i know that i already asked this question but, i did some thinking (good for me right :D) and i said that cuberoot(5)-cuberoot(3) is larger because because the space between the the points on the graph are further apart, or have a longer secant line. is that a fair assumption? the original question was...using the graph cuberoot(x) explain without using algebra whether cuberoot(5)-cuberoot(3) or cuberoot(7)-cube(5) is larger

    3rt(7) and 3rt(5) tend to be more level, and change less than 3rt(3) and 3rt(5)

    its good, but you gotta see it as the slope of the line; 5 to 7 changes little compared to 3 to 5

    so 5-3 has a smaller slope than the 7-5

    spose 2-2 = 0; 7 to 5 and 2-1 = 1; 5 to 3

    so it wants to me to create a similar question using a different function which im using e^x and my equation is e^3-e^2 which is greater then e^8-e^5
