-8 = -7x-1
bring -1 to the other side as we are isolating for x so it will be
-7 = -7x then divide -7 from each side
-7/-7 = (-7/-7)x
1 = x
Answer is f(1)= -8
Be sure to include the "=" sign: <span>f(x) = 2^x -7
To find the x-intercepts, set f(x) = 0 and solve for x: 2^x - 7 = 0,
or
2^x = 7
Take the common log of both sides: x log 2 = log 7
log 7
Solve for x: x = --------- = 2.81 (approx)
log 2

Answer:
Therefore Vertical Angles are
1. ∠ AFB and ∠ DFE
2. ∠ AFE and ∠ BFD
Step-by-step explanation:
Vertical Angles:
The angles opposite each other when two lines cross or intersect each other.
They are always equal.
The Two Lines are A-F-D and B-F-E
Lines A-F-D and B-F-E INTERSECT each other at point F.
Therefore Vertical Angles are
1. ∠ AFB and ∠ DFE
2. ∠ AFE and ∠ BFD
