<h3>Given:</h3>

f(x) = 5x^2 - 13

g(x) = 8x^3 + 4

<h3>To Find:</h3>

The value of (f+g)(x) or <u>f(x) + g(x)</u> .

<h3>Explanation:</h3>

By putting the respected values, we get

f(x) + g(x) = 5x^2 - 13 + 8x^3 + 4

By simplifying the like terms, we get

<u>f(x) + g(x) = 8x^3 + 5x^2 - 9</u>

<h2>Answer:</h2>

<u>(f+g)(x) = 8x^3 + 5x^2 - 9</u>

Step-by-step explanation:

<h3>Given</h3>
  • f(x) = 5x^2 -13 and g(x) =8x^3 +4
<h3>To find </h3>
  • (f+g)(x)
<h3>Solution</h3>
  • (f+g)(x) =
  • f(x) + g(x) =
  • 5x^2 -13 + 8x^3 +4 =
  • 8x^3 + 5x^2 - 9

Please help fast i have no clue what this is meaning<br> ILL MARK U BRAINLIEST

Answer:

A function is a relation that is either

  1. one-to-one, meaning each output only has one input
  2. many-to-one meaning some outputs can have more that one input, but all inputs only have one output

So, That pic is cramped, don't even know what functions are being referenced but

from the a, b, c, d relation

  • It is not a function because some inputs have more that one output, which fails our man-to-one rule

From the equations

  • -3x = 15 is not a function, because it only has one input but more than one output breaking rule 1
  • 2y=10 is a function because every input x has only one output y, it is many-to-one
  • 3x-0.25y=3 is a function, it is one to one

From the graph

  • the line is a function, since it is many-to-one

From the points

  • the x coordinate is the input, not points (2,6) and (2,3) have the same input for two outputs, breaking rule 2, that each input should have only one output. So the points are not a function

Simplify x^2-9x-22/x-11
OleMash [197]

Answer:

x^2-11/-8x

Step-by-step explanation:

We can solve this equation easily by using PEMDAS, or order of operations.

<u>Parenthesis</u>

<u>Exponents</u>

<u>Multiplication>Division (Depends on which comes first left to right)</u>

<u>Addition>Subtraction (See multiplication>division)</u>

Now that we know the order of the operations, we can solve.

First, we cant solve for x^2 because we dont know the value of x, so well leave that alone. Same with 22/x. All we can do is use the commutative property.

So our equation is now x^2-11/-8x

Hope this helps!
