X=7 and x+1=8 are two consecutive integers.
y = (9x) ^ (1/3)
exchange x and y then solve for y
x = (9y) ^ (1/3)
cube each side
x^3 = 9y
divide each side by 9
1/9 x^3 = y
the inverse function is 1/9 x^3
F(x)=-9/x which is equal to:
f(x)=-9x^(-1) So the power rule for differentiation is used...
Power rule: f(x)=x^e, df/dx=ex^(e-1) so:
df/dx=-9(-1)x^(-1-1)
df/dx=9x^(-2) or if you prefer...
df/dx=9/x^2
df/dx(6)=9/36=1/4
What you would do to “simplify” the equation is 18000-100 then divide by 50. The answer would be 358. Hoped this helped!
