This is calculus review, I wanna make sure I got #1 correct and I need help going through the other questions.

For the following functions, solve for the derivative with respect to x a. {(x) = bxaxz + 2 F '00 * to act! b. )'(x)=t1(23x)2 +b (Nod e. ham \"8.1x For each function in Question #1 above, what values of the parameter a will make the function convex? What values of a will make the function concave? Again using the functions from Question #1, assume that a = 2 and b = 4. For each function, at what value for x will the function have a slope of zero (Le. be flat)? For each function, does this value 0er maximize or minimize the function value? For the following functions, solve for the partial derivatives with respect to both at and y 3. KM?) = (4xx2) ' 0+2) b. f(x,y) = inyi For both functions in Question #4 above, assume that y z: 4. ls there a value ofx that will maximize the respective function? If the answer is "yes\
