Find f X g
3 sqrt of x+1 X x^3+1
I am assuming you really don't want the product of those functions; you want to know what the "function of a function", f{g(x)],is. To get that, substitute g(x) for x in the f(x) expression.
f(x) = 3 sqrt(x+1)
g(x) = x^3 + 1
f{g(x)] = 3 sqrt(x^3 +1 + 1)
= 3 sqrt(x^3 +2)
if 2^x=3 whats does 4^-x equal
To find f(X) * g(X), you need to multiply the two functions f(X) and g(X) together. In this case, the two functions are:
f(X) = 3 * sqrt(X + 1)
g(X) = X^3 + 1
To find f(X) * g(X), you simply substitute g(X) in place of X in f(X). Let's do that:
f(X) * g(X) = 3 * sqrt(g(X) + 1)
Now, substitute g(X) = X^3 + 1 into the equation:
f(X) * g(X) = 3 * sqrt((X^3 + 1) + 1)
Simplifying this equation further is not possible without specific values for X. However, you have the expression for f(X) * g(X) using the given functions.
