In this type of exercise ≥ values mean values that are inside the 'area' that the function is determining.

So the correct answer can only be now A or C because B and D are 'outside' areas.

In the letter A we can choose a point to validate the function. Let's choose the point (6,-4):

$y\ge x^2-7x+10$
$-4\ge6^2-7*6+10$
$-4\ge36-42+10$
$-4\ge4\text{ !!!}$

Look that this result is impossible. -4 is not greater than 4. This invalidate letter A! Therefore the correct answer will be the letter C.
