To find the critical points of a two variable function, find the partial derivatives of the function with respect to x and y. Then, set the partial derivatives equal to zero and solve the system of equations to find the critical points. Use the second partial derivative test in order to classify these points as maxima, minima or saddle points. Consequently, to determine the intervals where a function \(f\) is concave up and concave down, we look for those values of \(x\) where \(f''(x)=0\) or \(f''(x)\) is undefined. When we have determined these points, we divide the domain of \(f\) into smaller intervals and determine the sign of \(f''\) over each of these smaller intervals. If \(f ...The interval of concave down is #x in (0,1.21)# and the interval of concave up is #x in (1.21, +oo)# graph{sqrtx e^-x [-0.821, 3.024, -0.854, 1.068]} Answer linkGiven a parabola \(y=ax^2+bx+c\), depending on the sign of \(a\), the \(x^2\) coefficient, it will either be concave-up or concave-down: \(a>0\): the parabola will be concave-up \(a<0\): the parabola will be concave-down; We illustrate each of these two cases here: ...

Where, f - Focal length, d i - Image distance, d 0 - Object ...To determine whether a function is concave up or concave down using the second derivative, you can follow these steps: Find the second derivative of the function. This involves taking the derivative of the first derivative of the function. The second derivative is often denoted as f''(x) or d²y/dx². Identify the critical points of the function.Solution: Since f′(x) = 3x2 − 6x = 3x(x − 2) , our two critical points for f are at x = 0 and x = 2 . We used these critical numbers to find intervals of increase/decrease as well as local extrema on previous slides. Meanwhile, f″ (x) = 6x − 6 , so the only subcritical number is at x = 1 . It's easy to see that f″ is negative for x ...
