if y is x squared, what is the value of dy dx at x=2?
Assuming you intended to write dy/dx, the value would be given by 2x (the derivative of x^2) evaluated at x=2, so it is 4.
oh thx
To find the value of dy/dx at x=2, we need to take the derivative of y with respect to x.
Given that y = x^2, we can differentiate this function using the power rule for differentiation. The power rule states that if y = x^n, then dy/dx = n * x^(n-1).
Applying the power rule, we have:
dy/dx = 2 * x^(2-1)
= 2 * x
Now, substitute x=2 into the derivative expression:
dy/dx = 2 * 2
= 4
Therefore, the value of dy/dx at x=2 is 4.
