The parabola is the name of the type of function curve judging by how it looks the curve opens downward to negative infinty.

The axis of symmetry is the point at which the parabola is equal on each side.
This point is at x=-1.

The vertex is the highest point of the parabola this is at the coordinates (-1,9)

The x intercepts are the places at which the parabola crosses the x axis
these points are at x = 2,-4

The y intercepts are the places at which the parabola crosses the y axis.
This points is at y = 8.

Which pair of functions are inverses of each other?
klio [65]

f(x) = 10x -5 and g(x) = (x+5)/10  are inverses of each other , Option D is the correct answer.

<h3>What is a Function ?</h3>

A function is a mathematical statement which relates two variables , a dependent and an independent variable.

The inverse of a function is found by replacing every y by x and vice versa , and then solve for y

The equation

f(x) = 4/x - 3

or

y= 4/x -3

Replacing y by x

x = 4/y -3

x +3 = 4/y

y = 4/(x+3)

Which do not correlate with the given inverse

f(x) = 10x -5

y = 10x -5

for finding inverse

10y -5 = x

10y = x+5

y = (x+5)/10

g(x) = (x+5)/10

Therefore , Option D is the correct answer.

Save-The-Most           $0.28 / ounce
Spend-Less-Money    $0.27 / ounce
Cheap-Food                $0.3 / ounce

Thus, the final arrangement should be: (1) Spend - Less-Money, (2) Save-The-Most, (3) Cheap-Food, (4) Save-Some-More

BRIANILEST!!Rushawn lined up the interior angles of the triangle along line p below.
astra-53 [7]
Your answer would be the last option: What will happen to the individual sections cannot be determined, but the size of the two sections together increases.

This is because angles on a straight line add to 180°, so if angle C decreases, angles A and B must collectively increase to make up for the loss. For example, if C = 20° and it decreases to 15°, A + B + C would equal 175° and so A and B would need to increase to make it 180°.

The reason we can't determine what happens to the individual sections is that they could either both increase, or one could increase and one could decrease, as long as they collectively make up for the decreased angle.

I hope this helps! Let me know if you have any questions :)
