The critical points are where the slope is 0
take the derivitive
f'(x)=2x-2

find where it equals 0
0=2x-2
2=2x
1=x
at x=1
sub that back into original function to find the y value of the critical point
f(1)=1^2-2(1)+7
f(1)=1-2+7
f(1)=-1+7
f(1)=6

the point is (1,6)

Tcecarenko [31]

Answer:

Reason : by ASA , x = 36

Step-by-step explanation:

∠ABC = ∠EBD      (vertically opposite angle)

BC = BD = 54        (same length)

∠BAC = ∠BDE       (alternate interior angles)

By ASA , ΔABC ≅ ΔDBE

54 \times x = 36 \times 54\\\\x = 36
