Given f(x) = ā7x^2 ā 3 [f of x equals the square root of the quantity 7 x squared minus 3], which of the following are u(x) and g(u) such that f(x) = g(u(x)) [f of x equals g of u of x]?
W) u(x) = 7x^2 ā 3 and g(u) = āu
X) u(x) = āx and g(u) = 7uĀ² - 3
Y) u(x) = ā7x^2 ā 3 [u of x equals the square root of the quantity 7 x squared minus 3] and g(u) = āu
Z) u(x) = ā7x ā 3 and g(u) = uĀ²
āļøAnswer:W) u(x) = 7x^2 ā 3 AND g(u) = āu
