Sent a pic of the solution (s). When it asked to factor out the coefficient of the variable just divide both numbers by the coefficient, and present it on the outside like I showed you.
Answer:
B
Step-by-step explanation:
Since we are given that f(x)=1, we just have to find what value of x gives 1 as the result.
From the graph, we can see that (0,1) gives 1 as a y-value. Thus, when x is 0, y is 1.
Therefore, f(0)=1.
So, our answer is B.
And we're done!
Answer:
a) Upwards
b) x = -1
c) (-1,-9)
d) x intercepts; (2,0) and (-4,0)
y intercept is (0,-8)
Step-by-step explanation:
a) As we can see, the parabola faces upwards
b) To find the axis of symmetry equation, we look at the plot of the graph and see the point through the vertex of the parabola that exactly divides the parabola into two equal parts
The x-value that the line passes through here is the point x = -1 and that is the equation of the axis of symmetry
c) The vertex represents the lowest point of the circle here,
As we can see, this is the point through which the axis of symmetry passes through to make a symmetrical division of the parabola
We have the coordinates of this point as
(-1,-9)
d) The intercepts
The x-intercept are the two points in which the parabola crosses the x-axis
We have this point as 2 and -4
The x-intercepts are at the points (2,0) and (-4,0)
For the y-intercept; it is the y-coordinate of the point at which the parabola crosses the y-axis and this is the point (0,-8)
Well slope means <span>a surface of which one end or side is at a higher level than another; a rising or falling surface.</span> So pretty much its just saying he had 6 litters used 4 of those litters and had a remainder of 2. So you can say the slope means that he was decreasing in litters by using 2 litters every 1 hour. I don know really if it´s correct so, sooopppeeerrrr sorry. :( :) bye
