Move all terms not containing U to the right side of the equation.
Exact Form:
U = 1/2
Decimal Form:
U = 0.5
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
</span>
<span>f(x)= -2x +1 for f(3)
f(3) = -2(3) + 1 = -5
answer
</span><span>A)-5</span>
