No real zeros for the function.

Explanation:

zero of a function f, if f(r) = 0

solve:

$\sf y=(x-20)^2 +5$

so when f(y) = 0

$\hookrightarrow \sf (x-20)^2 +5 = 0$

$\hookrightarrow \sf (x-20)^2 = -5$

$\hookrightarrow \sf (x-20) = \sqrt{-5}$

$\hookrightarrow \sf x = \pm \sqrt{-5} +20$

$\hookrightarrow \sf x = \sqrt{-5} +20, \ \sf x = -\sqrt{-5} +20$

check:

$\hookrightarrow f \sf (\sqrt{-5} +20) = Not \ applicable$ , $f \sf (-\sqrt{-5} +20) = Not \ applicable$
