It is a diverging mirror with the following convex mirror equation: \frac {1} {u} + \frac {1} {v} = \frac {1} {f} u1 + v1 = f 1. , so the lens mirror equation is basically the same as for concave mirrors.Scientific Calculator.

Solution. We see that the function is not constant on any interval. The function is increasing where it slants upward as we move to the right and decreasing where it slants downward as we move to the right. The function appears to be increasing from \displaystyle t=1 t = 1 to \displaystyle t=3 t = 3 and from \displaystyle t=4 t = 4 on. Options.

The first derivative tells us if a function is increasing or decreasing. If \( f'(x) \) is positive on an interval, the graph of \( y=f(x) \) is increasing on that interval.. If \( f'(x) \) is negative on an interval, the graph of \( y=f(x) \) is decreasing on that interval.. The second derivative tells us if a function is concave up or concave downTo determine concavity, analyze the sign of f''(x). f(x) = xe^-x f'(x) = (1)e^-x + x[e^-x(-1)] = e^-x-xe^-x = -e^-x(x-1) So, f''(x) = [-e^-x(-1)] (x-1)+ (-e^-x)(1) = e^-x (x-1)-e^-x = e^-x(x-2) Now, f''(x) = e^-x(x-2) is continuous on its domain, (-oo, oo), so the only way it can change sign is by passing through zero. (The only partition numbers are the zeros of f''(x)) f''(x) = 0 if and only ...

Concavity and convexity. For the analysis of a function we also need to determine where the function is concave or convex. In other words, we need to determine the curvature of the function. We say that a function f is concave on an interval ( a, b) if for all x ∈ ( a, b) f ″ ( x) < 0 . On the contrary, we say that a function f is convex in ...Second Derivative and Concavity. Graphically, a function is concave up if its graph is curved with the opening upward (Figure \(\PageIndex{1a}\)). Similarly, a function is concave down if its graph opens downward (Figure \(\PageIndex{1b}\)). Figure \(\PageIndex{1}\) This figure shows the concavity of a function at several points.

The sign of the derivative tells us whether the curve is concave downward or concave upward. Example: Lets take a curve with the following function. y = x³ − 6x² + 12x − 5.Let's look at the sign of the second derivative to work out where the function is concave up and concave down: For \ (x. For x > −1 4 x > − 1 4, 24x + 6 > 0 24 x + 6 > 0, so the function is concave up. Note: The point where the concavity of the function changes is called a point of inflection. This happens at x = −14 x = − 1 4.If f '' 0 on an interval, then f is concave down on that interval. If f '' changes sign (from positive to negative, or from negative to positive) at some point x = c, then there is an Inflection Point located at x = c on the graph.
