WebNov 30, 2015 · How to evaluate a function? Here we know that h (x) = -2x - 10, and we want to find h (-4). This just means that we need to replace the "x" on the above function by a -4. We will get: h (-4) = -2* (-4) - 10 Remember that the product of two negative numbers is positive: h (-4) = -2* (-4) - 10 = 8 - 10 = -2 h (-4) = -2 WebWell, f of x is equal to the square root, of x squared minus one. x squared minus one. So it's gonna be that over 1, plus the square root. One plus the square root of x squared minus one. So this is a composition f of g of x, you get this thing. This is g of f …

WebOct 4, 2015 · f (x) = x2 − 2x + 3. Then: f (a + h) − f (a) h. = ((a +h)2 − 2(a +h) +3) − (a2 −2a +3) h. = a2 + 2ah +h2 − 2a −2h + 3 − a2 + 2a − 3 h. = 2a −2 +h. So: lim h→0 f (a +h) −f (a) h = lim h→0 (2a − 2 + h) = 2a − 2. This is the derivative of f (x) at x = a. WebSolve an equation, inequality or a system.
