What is the domain of the function y=^x=6-7?
2 answers:
Answer:
<h2>The domain would be -1</h2>Step-by-step explanation:
The given function is
This expression expresses that both expressions are equal, that is
So, basically the function can be expressed as . In other words, the function is only a point.
Therefore, the domain would be -1 and the range -1. Because the only element for <em>x </em> is -1 and the only element for y is -1.

Answer:
48 ft
Step-by-step explanation:
For the quadratic ax^2 +bx +c, the axis of symmetry is x = -b/(2a). For the given quadratic, which defines a parabola opening downward, the axis of symmetry defines the time at which the maximum height is reached.
t = -48/(2(-16)) = 1.5
Then the maximum height is ...
f(1.5) = (-16·1.5 +48)1.5 +12 = (24·1.5) +12
f(1.5) = 48
The maximum height the object will reach is 48 feet.
