Plese give the better answer of the question given below?

Question

(a) Differenciate, Y w.r.t. X where, Y=e^(log tan x^4)^2.
(b) find : lim of x to endless 23x^3+45^x/78x^3+9.
(c) If f(x)= medium brace x, if x is an integer and 10-x if x is a real number.
(d) for the following function, find a point of Maxima and a point of minima, if these exist: f(x)=17x^5-14x^3+44.

Answer 1

(e) quit posting your requests for cheating on this site.

Answer 2

(a) don't know what w.r.t. means

(b) do you mean 23x^3 + (45^x/78x^3) + 9 or [23x^3 + 45^x]/[78x^3 + 9]? either way, 45^x goes to ∞.

(c) assuming you are defining a piecewise defined function (and where is the question?), your definition is contradictory: all integers are real numbers.

(d) max and min where d(f(x)/dx = 0, so 85x^4 - 42x² = 0
x²(85x² - 42) = 0
x = 0 or
x = ±√(42/85)
