Find the first 2 derivatives of f(x) = 9x²

^{Then solve please}

Solution

given : f(x)=9x^2

first derivative: f\'(x)=18x

Second derivative: f\'\'(x)=18

you can use the method I used whre you multiple the exponent number by the constant to the side of the x and then subtract the exponent by one.

For example for the first derivative you muliply 9 times 2 = 18

you also subtract 1 from the 2 resulting in simply: x

so you have first derivative = f\'(x)=18x

To solve for the second derivative you simply repeat this process to get f\'\'(x)=18
