Answer:
=71
Step-by-step explanation:
With x = 4, just subsitute (19x-5) to (19(4)-5) which, coming down to PEMDAS, results to 71, since 19x4= 76-5= 71.
Hope this helps!
Answer:
g(f(x)) =3(x2)+1
Step-by-step explanation:
g(f(x)) means substitute f(x) in the eqn g(x)
That is anywhere you see x2, use it to replace x in the eqn g(x)

<h2>Determining if a Relation is a Function or not</h2><h3>
Answer:</h3>
1: Function
2: Not a Function
<h3>
Step-by-step explanation:</h3>
We consider a Relation to be a Function if one input from the Domain corresponds to only one output from the Range or multiple inputs from the Domain corresponds to only one output from the Range.
Part 1:
Given:
We can see from the given table that there's no input from the Domain that corresponds to multiple outputs from the Range. We can only see multiple inputs, and from the Domain that corresponds to only one same output from the Range, . So, we consider this relation a function.
Part 2:
<em>Please</em><em> refer</em><em> to</em><em> the</em><em> </em><em>image</em><em> </em><em>for</em><em> the</em><em> </em><em>Given</em><em> </em><em>Graph</em><em>.</em>
If we consider to be Domain and to be Range, we can see for the same input, , it corresponds to <em><u>infinite</u></em> outputs. Other way of view this is that consider the point , no matter what real values of the output, , the point will still be on the line. So, this graph is not a function.
