Answer:

Step-by-step explanation:

Domain : Set of all possible input values (x-values) on a graph

Codomain : Set of all possible out values for the input values (y-values) on the graph

Range : Actual output values for the input values (x-values) given on the graph.

Therefore, for the given graph,

Domain : (-∞, ∞)

Codomain : (-∞, 2]

Range : (-∞, 2]

From the given graph every input value there is a image or output value.

Therefore, the given function is onto.

hope that this answers your problem !

To solve this question, we first need to layout the equation

-2 1/2 -(-1 3/4)

Step 1

-2 1/2-(-1 3/4) ... Equation

Step 2

5/2-(-1 3/4) ... Converted to improper fraction

Step 3

5/2-(-7/4) ... converted to improper fraction

Step 4

5/2--7/4 ... Got rid of parenthesis

Step 5

-3/4 ... Subtract

Answer:

-3/4 ... Answer

So the answer for this problem is C, -3/4

F(n)=5.(-2)n-1<br>Complete the recursive formula of f(n).

Alex73 [517]

Answer:

a(n) = $(-2)(a_{n-1})$

$a_{1}=5$

Step-by-step explanation:

The given expression is in the form of the explicit formula of a geometric sequence.

f(n) = $a(r)^{n-1}$

Where 'a' = First term of the sequence

r = common ratio

Recursive formula of a geometric sequence is,

a(n) = $(a_{n-1}).(r)^{n-1}$

a(n) = $(-2)(a_{n-1})$

Where, $a_{1}=5$

So the recursive formula will be a(n) = $(-2)(a_{n-1})$

What is the equation for this graph pls help me and pls make sure it’s right:))

SVETLANKA909090 [29]

Answer:

y = 5x + 4

Step-by-step explanation:

First I found the slope by using the the definition that slope is rise/run so I saw that the y value went up from 4 to 9 which is 5 units and then the x value went up one in that same time. This means that the slope is 5/1. Then I found the y intercept by seeing where x = 0. On the graph you can see the line touches the y - axis at a value of 4 which means that the y - intercept is 4. Plugging these values into the y = mx + b equation you get y = 5x + 4.
