Question

Please helppppp!! I kept trying to get the answer but I’m stuck!!

Answer 1

The solution of the expression is

w (u (x)) = √9

u (w (x)) = 3²

How to find the expressions

The equation is solved as follow

Given that

u (x) = x² + 5

w (x) = √(x + 3)

First case: u (w (x))

w (u (x)) = √(x² + 5) + 3)

w (u (x)) = √(x² + 5 + 3)

w (u (x)) = √(x² + 8)

for x = 1

w (u (x)) = √9 = 3

Second case: w (u (x))

u (w (x)) = (√(x + 3))² + 5

u (w (x)) = x + 3 + 5

u (w (x)) = x + 8.

For x = 1

u (w (x)) = 9

u (w (x)) = 3²
