For f(x)=cosx+sinx, determine all of the values of x for which f(x)=0

Define f (x) = 2 – 3x2. Find the exact value of f (). 1

Let the function f: RR be defined by 1 x2, f(x) = { x=0, x = 0.

Let y = f(x) = (4√x+6) (6√x+8) (7√x + 6). Find the derivative function f(x) and evaluate it at x = 1. = f(x)\x=1 da
