1. The graph is a parabola.
2. The parabola opens up, because there's no negative number in front of .
3. The vertext is (5,-1), because of the vertex form.
This means that that -1 will be the least y-value used on the graph and the garph will open up from there.
The range is (-1, infinity) or { y | y > -1 }.
Answer:
y is also doubled.
Step-by-step explanation:
Direct proportionality between and
means that
or
,
which indicates a linear relationship between and
because they are related by a constant.
Therefore, if x is doubled, then the new value of is
The new value of is 2 times the previous; therefore,
is doubled as
is doubled.
