Step-by-step explanation:
4x=3×8
4x=24
x=24÷4
x=6
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
Answer:
1/4
Step-by-step explanation:
6/9*3/8=18/72=1/4
