Answer:

Step-by-step explanation:
Sometimes the quadratic is easier to graph if written in vertex form.
y = -x^2 -6x -3
= -(x^2 +6x) -3
= -(x^2 +6x +9) -3 +9
= -(x +3)^2 +6
This is a parabola that opens downward, with its vertex at (-3, 6). Unlike the one shown in the graph already, its scale factor is 1, so it will appear narrower than the one given with the problem statement.
Answer:
The hiking club's member count increased by 48%.
Step-by-step explanation:
We are given two data values: 25 members and 37 members. We need to determine how many members the club gained first. We can set up an equation where we solve for an unknown, or<em> x</em>, in this case.
The club increased by 12 members, so now we can divide this value by the initial amount of members and multiply the decimal we receive by 100 to express it in percentage form.
Therefore, the club's member count increased by 48%.
