Answer:
2
Step-by-step explanation:
You don't have the graph icon here, so we'll have to graph this parabola without it.
Your parabola is y = -x^2 + 3., which resembles y = a(x-h)^2 + k. We can tell immediately that this parabola opens down and that the vertex is (0,3).
Plot (0,3). Besides being the vertex, this point is also the max. of the function.
Now calculate four more points. Choose four arbitrary x-values, such as {-2, 1, 4, 5} and find the y value for each one. Plot the resulting four points. Draw a smooth curve thru them, remembering (again) that the vertex is at (0,3) and that the parabola opens down.

Well, here is the mean of ur data collected 48.181818...
Which of the digits are underlined ?
if it’s the first 7 it’s 7 ones
if it’s the 2 it’s 2 tenths
if it’s the last 7 it’s 7 hundredths
<u>Solution</u>:
3y = -9x - 22
y = -3x - 22/3
The graph parallel to this graph (9x + 3y = -22) should have a gradient of -3
In the choices above i.e A,B,C & D there is not a single equation with a gradient equal to -3.
