Answer:

[tex]x=1[/tex] is a critical point of the function [tex]f(x).[/tex]

Step-by-step explanation:

[tex]f(x)=x^2-2x+7[/tex]

Differentiate both sides w.r.t. [tex]x[/tex]

[tex]\Rightarrow f'(x)=2x-2[/tex]

Now, [tex]f'(x)=0[/tex]

[tex]\therefore 2x-2=0[/tex]

[tex]\Rightarrow 2x=2[/tex]

[tex]\Rightarrow x=1[/tex]

Hence, [tex]x=1[/tex] is a critical point of the given function.
