Question

Find the indicated function value, if it exists, given f(x) =2-x and g(x)= sqrt3-x.

(f+g)(-3)

Answer 1

Hi!

given \(\sf f(x) =2-x\) and \(\sf g(x)= \sqrt{3-x}\) and x=-3

they are asking for \(\sf (f+g)(-3)= f(-3)+g(-3)\)
evaluate \(\sf f(-3)+g(-3)\)
\(\sf f(-3)+g(-3) =2- (-3) +\sqrt{3-(-3)} \\=2+3+\sqrt{3+3}\\=?\)

Answer 2

\[5+\sqrt{6} ?\]

Answer 3

yes that would be right :)
