F x find f x
WebTo evaluate f (x) at x = 2, I'll plug 2 in for every instance of x in the function's rule: f (2) = (2) 2 +2 (2) − 1 To keep things straight in my head (and clear in my working), I've put parentheses around every instance of the argument 2 in the formula for f. Now I can simplify: (2) 2 + 2 (2) − 1 = 4 + 4 − 1 = 7 Then my answer is: f (2) = 7 WebFind the intervals on which f(x) is increasing, the intervals on which f(x) is decreasing, and the local extrema.5x^4-160x^3+2; Question: Find the intervals on which f(x) is increasing, the intervals on which f(x) is decreasing, and the local extrema.5x^4-160x^3+2

You'll get a detailed solution from a subject matter expert that helps you learn core concepts. See Answer Question: Let f (x) = x - 1 and g (x) = x² – x. WebAt a point x = a x = a, the derivative is defined to be f ′(a) = lim h→0 f(a+h)−f(h) h f ′ ( a) = lim h → 0 f ( a + h) − f ( h) h. This limit is not guaranteed to exist, but if it does, f (x) f ( x) is said to be differentiable at x = a x = a. Geometrically speaking, f ′(a) f ′ ( a) is the slope of the tangent line of f (x) f ( x) at x = a x = a.
