I’m doing math homework and is about functions they said f(x)= x-3 and g(x)= √x-2

After I set them up I have this
am I supposed to just add the numbers or is there something else to do?

√ (x-3)-2

Answer: It looks like you are trying to find the value of the function h(x) = √ (x-3) - 2.

To find the value of this function for a given value of x, you need to substitute the value of x into the function definition and simplify the expression.

For example, if you want to find the value of h(x) for x = 5, you would substitute 5 for x in the function definition and simplify the expression to get:

h(5) = √(5-3) - 2

= √2 - 2

= 1.4 - 2

= -0.6

Therefore, the value of h(x) for x = 5 is -0.6.

You can follow this same process to find the value of h(x) for any other value of x. Just be sure to substitute the correct value of x into the function definition and simplify the expression to find the final result.

Answer:

g[f(x)]

Explanation:

Given functions:


f(x)=x-3


g(x)=√(x)-2

Composite functions are when the output of one function is used as the input of another.

Therefore, to create √(x-3)-2, substitute the function f(x) in place of the x in function g(x):


\begin{aligned}\implies g[f(x)]&=√(f(x))-2\\&=√(x-3)-2\end{aligned}
