WebOct 20, 2024 · Let's go through and look at solving this polynomial: f ( x) = ( x - 7) ( x + 1) ( x - 2). This polynomial is already in factored form, so finding our solutions is fairly straightforward. We set ... WebApr 12, 2024 · Step 5. Choosing a point to the left of x = 0 x = 0, say x = -1 x = −1, we find that f’’ (-1) = 6 + 6 = 12 f ’’(−1) = 6 + 6 = 12. So, we can put a plus sign to the left of x = 0 x = 0. Since f’’ (x) > 0 f ’’(x) > 0, this means that f f is concave up on the interval (- …

Find the domain of the function using WebOn the graph of a line, the slope is a constant. The tangent line is just the line itself. So f' would just be a horizontal line. For instance, if f(x) = 5x + 1, then the slope is just 5 everywhere, so f'(x) = 5. Then f''(x) is the slope of a horizontal line--which is 0. So f''(x) = 0. See if you can guess what the third derivative is, or the ...

WebDec 21, 2024 · An absolute extremum may be positive, negative, or zero. Second, if a function f has an absolute extremum over an interval I at c, the absolute extremum is f(c). The real number c is a point in the domain at which the absolute extremum occurs. For example, consider the function f(x) = 1 / (x2 + 1) over the interval ( − ∞, ∞). images of infant bath tubsWebf(x) = cos2 x−2sinx, 0 ≤ x ≤ 2π. (a) Find the intervals on which f is increasing or decreasing. Answer: To find the intervals on which f is increasing or decreasing, take the derivative of f: f0(x) = 2cosx(−sinx)−2cosx = −2cosx(sinx+1). Since sinx+1 ≥ 0 for all x, we see that the sign of f0(x) is the opposite of that of cosx. list of all important daysWebThe intersection of two intervals is the set of all values that are common to both intervals.
