Question

Use the graph of the function to find, f(2).
-2
-1
1
2

Answer 1

graph

Answer 2

f(2) means that the x value of the function point would be on 2
when x = 2 what would y equal to according to your graph ?

Answer 3

1?

Answer 4

Correct

Answer 5

Alright easier then I thought, just a little confused researched what it meant and you helped too thanks again!

Answer 6

you welcome

Answer 7

@Will.H One thing that I was wondering if you know, How can you find the domain and range from the vertex?

Answer 8

could you explain what exactly the question is and if there's a function, that would help

Answer 9

@Will.H The graph of an absolute value function opens down and has a vertex of (-3,0).

Answer 10

The vertex has been a weak point for me in a few assignments because of variations of this question.

Answer 11

Great..
So you do know that the Domain is all inputs (x values) of the function
Range is all outputs (y values) of the function
since it is OPENS DOWN that means the maximum value (vertex) is (-3,0)
So since we said the maximum value then that would means that the domains (x values) of the function is all real numbers less than or equal to -3

and the range is all y values less than or equal to 0

hope that helps

Answer 12

so [-3,infinity) for domain and (-infinity,0] for range @Will.H

Answer 13

Agan if there's a graph or a diagram or at least a real function i would be able to help you better

Answer 14

@Will.H They didn't give me anything else but still thank you

Answer 15

you welcome just know that the domains and ranges vary from function to another (types)
in linear function it is easy to determine the domain and range in exponential function and polynomials it would take some work
in your question am sure it is exponentiaal or polynomial since you mentioned vertex so i can't help you any further because i don't have the function sorry :)

Answer 16

let me know if i can help with anything else
