Use the information to evaluate and compare δy and dy. (round your answers to four decimal places.)
y = x4 + 4 x = −2 δx = dx = 0.01

Step-by-step explanation:

To compare both expression, we recur to the formulas

Replacing given values in each expression, we have:

Now, to find dy, we first have to derivate the function

Then, we apply the formula

Therefore, the differentials are

r and t.

both are 64 degrees.
