Determine the domain and range of the given function.
2 answers:
Answer:
The domain is all real numbers
The range is all real numbers greater than or equal to
Step-by-step explanation:
we know that
The function in the figure is a vertical parabola
The vertex of the function is the point
The parabola open upward------> the vertex is a minimum
The domain is the interval------> (-∞,∞)
The domain is all real numbers
The range is the interval------> [-2,∞)
The range is all real numbers greater than or equal to

That Parabola's equation is
Step-by-step explanation:
I can't really explain much, but the top equation is a formula for <em>all </em>equations for a parabola. h and k are the x and y-values of the vertex. a is, well, a.
How did I find the equation of the parabola? Simple. Since the vertex is on the origin, h and k are 0. Also, because it intercepts (2,4) and (1,1), a=1.
