Question

Differentiate the function

Answer 1

\[y=\sqrt{x}(x-4)\]

Answer 2

you can multiply out and get
\[\large y=x^{\frac{3}{2}}-4x\] then use the all mighty power rule

Answer 3

you got that or no?

Answer 4

so i put 3/2 in front of x and subtract one from the exponent

Answer 5

zactly

Answer 6

the exponent would be 1/2 correct?

Answer 7

yes

Answer 8

so this is what I got \[y=\frac{ 3 }{ 2 }x ^{\frac{ 1 }{ 2 }}- 4\]

Answer 9

yes

Answer 10

which you could also write as
\[y'=\frac{3}{2}\sqrt{x}-4\] if you like

Answer 11

the hardest part of calc one is adding and subtracting fractions

Answer 12
