First we use product rule
y=x^2lnx
dy/dx = x^2 d/dx (lnx) + lnx d/dx (x^2)
dy/dx = x^2 (1/x) + lnx (2x)
dy/dx = x + 2xlnx
now taking second derivative:
d2y/dx2 = 1 + 2[x (1/x) + lnx (1)]
d2y/dx2 = 1 + 2[1+lnx]
1+2+2lnx
3+2lnx is the answer
Answer: The answer is A. -21
Its simplified and i just multiplied 3 by -7 :)
29/4 hopes this help sorry if I’m wrong
Answer:
A) 10.00
Step-by-step explanation:
10.00 x 0.8 is equal to 8 giving a total of 18.00. But it is incorrectly done in the table.
Answer: 
Step-by-step explanation:
I hope you mean y = x² - 12 and not y = 2x - 12.
You switch the y and x variables:
x = y² - 12
And solve for y:
x + 12 = y²
