first one is your answer
y intercept:
f(x) = x^2 -5x + 6
x = 0, y =6
g(x) = f(x/2) = (x/2)^2 -5x/2 + 6
x = 0, y = 6
both f(x) and g(x) has same y intercept : 6
x intercept when y = 0
x^2 -5x + 6 = 0
(x-3)(x-2) = 0
x - 3 = 0, x =3
x - 2 = 0, x = 2
so f(x) has x-intercepts 3 and 2
From here, you do not need to calculate x-intercept s of g(x)
You can determine the answer is A. first one
