<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>

Answer:

  • (f+g)(x) = 8x^3 + 5x^2 - 9

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

Answer:

Analyzed and Sketched.

Step-by-step explanation:

We are given y=\frac{\ln\left(5x)}{x^2}

To sketch the graph we need to find 2 components.

1) First derivative of y with respect to x to determine the interval where function increases and decreases.

2) Second derivative of y with respect to x to determine the interval where function is concave up and concave down.

y'=\frac{1-2\ln\left(5x)}{x^3}=0

x = \sqrt e/5 is absolute maximum

y''=\frac{6\ln\left(5x)-5}{x^4}=0

x=e^{5/6}/5 is the point concavity changes from down to up.

Here, x = 0 is vertical asymptote and y = 0 is horizontal asymptote.

The graph is given in the attachment.
