What is the domain of the quadratic function graphed below?
lora16 [44]

The domain of the graph is the set of all real values

<h3>How to determine the domain?</h3>

The domain is the set of x values of the graph

From the graph, the x values extend in both directions without end

This means that the x values can accommodate all real values

Hence, the domain of the graph is the set of all real values

Please help I need it by tonight

Using mathematical operations we can conclude that the area of the given figure is 40 units².

<h3>What are mathematical operations?</h3>
  • An operation is a function in mathematics that transforms zero or more input values into a clearly defined output value.
  • The operation's arity is determined by the number of operands.
  • A mathematical action is called an operation.
  • Mathematical operations include addition, subtraction, multiplication, division, and finding the root.

So, the area of the figure:

Where x = 4, so the expression will become:

  • x² + x² + x + x

Now, do the mathematical operations to get the area of the figure as follows:

  • x² + x² + x + x
  • 4² + 4² + 4 + 4
  • 16 + 16 + 8
  • 40

'

Therefore, using mathematical operations we can conclude that the area of the given figure is 40 units².

0.12 = 12 hundredths

34.12 would be the answer.
