Answer:
The domain of the function is the set of all real numbers; the range of the function is the set of all nonnegative real numbers; the graph has an intercept at (0, 0); and the graph is symmetric with respect to the y-axis.
Step-by-step explanation:
This is not a square root function, this is a quadratic function, which has an x².
The domain, or set of x-values, is all real numbers. This is because all numbers work for x.
The range, or set of y-values, is the set of all nonnegative real numbers. This is because all numbers we get for y are positive real numbers.
The graph intersect both the x- and y-axis (x-intercept and y-intercept) at (0, 0).
The graph is decreasing on the interval x<0 and increasing on the interval x>0, not the other way around.
The graph has a minimum at (0, 0), not a maximum.
The graph can be folded in half along the y-axis, so it is symmetric with respect to the y-axis.
Answer:
Y=2/3
Step-by-step explanation:
Y varies directly as X
Y=k x
K is a constant
6=k72
K=1/12
Y=1/12x
Y=1/12×8
y=2/3
Answer:
A little hard to read but if i read correcly the answer shoulkd be 14$
Step-by-step explanation:
Answer:
The answer is 7 sides and 2 bases.
Step-by-step explanation:
This is a seven (7) sided shape on its lateral
Then we have a top and a base making it a nine (9) altogether for Surface area.
Because it is a polygon just like a prism we only see its shape on the base when you tilt it, so the top of the net is drawn can also be drawn on its side. See attached last few pages.
We draw it on its base so we can see both the cross section is vertical and slice the heptagon. Here we can call it a vertical heptagon prism. As its on its base the height would be high to low and look like a watch on the arm whilst the arm is reaching for the door. The measurements of the bases would be 2x the height at its longest point on the actual top and base. (As long as they are not more than 2x it would represent the shape when it becomes a prism.
All the pictures may not be relevant but it helps you understand area 1/2 x 1 = 1/2 so 1/2 x 2cm = 1 and 2 x 2 = 4 for other shapes.
We cna use these measurements when showing the bases are twice the size and also label height H = 2cm and Length = 4cm
For the heptagon. The area is worked out a different way but this may help you get used to multiplying half when working with shapes.
