The position of an object at the time t is given by s(t) = -8 - 9t. Find the instantaneous velocity at t = 1 by finding derivative.

Find the limit of the function algebraically. (sorry I don't know how to use the insert equation)

lim x² + 3 / x⁴

x->0

Determine if the graph is symmetric about the x-axis, the y-axis, or the origin.

r= 2 cos 3
