this is wrong. but can you explain how to correct it? thanks use differential of x^-1/3 to approximate solution to (1/cube root(7.952)) differential: df= -1/3(x^(-4/3)) * dx df= -1/48 * 0.0048 df= -0.001 0.500 - 0.001 = 0.499 but this is wrong.

use differentials to approximate the change in f(x) if x changes from 3 to 3.01 and f(x) = (3x^2-26)^10 derivative: 10(3x^2-26)^9 f(x+ delta x)= 1 + 10(3x^2-26)^9 * 0.01 = 1 + 10(0.01) <-- Substitute 3 for x = 1 + 0.1 = 1.1 delta y= 1.1 - 1 delta y= 0.1 b...

calculate delta y for f(x)= x^(3/2) with x= 4 and delta x= dx=0.1 delta y= f(x+delta x)- f(x) = f(4.1) - f(4) delta y= f(4.1)-8 f(x + delta x)= 8 + 3/2*x^(1/2)*0.1 = 8 + 0.15x^(1/2) = 8 + 0.30 = 8.30 delta y= 8.30 - 8 delta y= 0.30 but this is wrong. why...

f(x)= 2x/(x^2+1) Vertical: none Horizontal: none Minimum: x=-1 Maximum: x=1 Inflection Points: it seems like there are one or two, but i don't know how to factor f''(x)= 4x^3 + x^2 - 12x + 1 :/

perpendicular lines have opposite sign and reciprocal slopes from the original line you are given. put the first equation into proper form y= (-2x/3)+(5/3) the slope in this case is -2/3 Therefor a perpendicular line will have the slope 3/2.
