Answer:
D) left a units, down b units
Step-by-step explanation:
Changes close to x, affect the horizontal, left/right movement (but sort of the opposite direction than you would expect.... + left move and - right move)
A number tacked on to the end of the equation moves the curve up or down as you would guess (+ up and - down)

Answer:
length of rectangle = 5
width of rectangle = 5
Area of rectangle = 25
Step-by-step explanation:
Since the length of the rectangle is "x", and the value of the area is given by the product of the length "x" times the width "10-x", indeed, the area "y" of the rectangle is given by the equation:

Now, they tell us that the area of the rectangle is such that coincides with the maximum (vertex) of the parabola this quadratic expression represents. So in order to find the dimensions of the rectangle and therefore its area, we find the x-coordinate for the vertex, and from it, the y-coordinate of the vertex, which is the rectangle's actual area.
Recall that the formula for the x of the vertex of a quadratic of the form :

is given by the formula:

which in our case gives:

Therefore, the length of the rectangle is 5, and its width (10-x) is also 5.
The area of the rectangle is therefore the product of these two values: 5 * 5 = 25
Which should coincide with the value we obtain when we replace x by 5 in the area formula:

Answer:
Option B (1,10)
Step-by-step explanation:
we have

we know that
If a ordered pair is on the graph of f(x) then the ordered pair must satisfy the function f(x)
<u><em>Verify each case</em></u>
case A) (0,0)
For x=0

Compare the value of f(x) with the y-coordinate of the ordered pair

therefore
The ordered pair is not on the graph of f(x)
case B) (1,10)
For x=1
Compare the value of f(x) with the y-coordinate of the ordered pair

therefore
The ordered pair is on the graph of f(x)
case C) (0,10)
For x=0

Compare the value of f(x) with the y-coordinate of the ordered pair

therefore
The ordered pair is not on the graph of f(x)
case D) (10,1)
For x=10

Compare the value of f(x) with the y-coordinate of the ordered pair

therefore
The ordered pair is not on the graph of f(x)
