Answer:
∠ DFC = 80°
Step-by-step explanation:
See the attached figure.
Since BFE is a straight line so, ∠ BFA + ∠ AFE = 180°
Now, ∠ AFE is given to be 125°.
So, ∠ BFA = 180° - 125° = 55°
Now, AFD is a straight line. So, ∠ BFA + ∠ BFC + ∠ DFC = 180°
⇒ 55° + 45° + ∠ DFC = 180° {Since, ∠ BFC is given to be 45°}
⇒ ∠ DFC = 180° - 55° - 45° = 80° (Answer)
The values produced by the function
will not be any lower than -7, but may be that low when x=-3.
That is, the range is
... f(x) ≥ -7 . . . . matches the 1st selection
