It would be less then (<) because when u multiply by a number less then 1, it becomes smaller

Anything times 1 is equal to itself. Anything times less than one is less than itself. Anything times greater than one is greater than itself. Therefore, 125 times .9, which is less than one, is less than 125

Which of the following relations is a function?

MrMuchimi

Answer:

A. (1,4), (-5, 2), (7, 1), (-8, 2)

Step-by-step explanation:

Definition of a Function

A function is a relation between an input and an output set of values with the condition that every element in the input set relates only to one element in the output set.

From the four options presented in the question, we must select the only one that doesn't repeat the value for x and has a different value of y.

For example, the set

B. (1,4), (-5, 6), (1, 3), (-8, 2) is not a function because the input value of 1 has two different output values

C. (1,0), (-5,3), (7, 1), (-5,5) is not a function either because the input value of -5 has two different output values

The correct choice is:

A. (1,4), (-5, 2), (7, 1), (-8, 2)

1.- What type of parabola is this?

xz_007 [3.2K]

Answer:

Part 1

Sideways or "horizontal" parabola with a horizontal axis of symmetry.

Part 2

The vertex is the turning point: (-3, 1)

Part 3

Vertex form of a horizontal parabola:

$x=a(y-k)^2+h$

where:

(h, k) is the vertex
a is some constant
If a > 0 the parabola opens to the right.
If a < 0 the parabola opens to the left.

Point on the curve: (-1, 2)

Substituting the vertex and the found point into the formula and solving for a:

$\implies -1=a(2-1)^2-3$

$\implies -1=a-3$

$\implies a=2$

Part 4

Equation for the given parabola in vertex form:

$x=2(y-1)^2-3$

Equation in standard form:

$x=2y^2-4y-1$
