PLEASE HELP ANSWER THIS QUESTION I DON'T KNOW IT AT ALL
Lena [83]

<h2><u>PLEASE MARK BRAINLIEST!</u></h2>

Answer:

  1. Is y = 4x - 7 a linear function?
  2. Is y = 6x² - 1 a linear function?
  3. Is y = \frac{1}{2x} + 10 a linear function?

Step-by-step explanation:

  1. Yes it is - when you graph this equation, it results in a [straight] line, signalling that it is a linear function.
  2. No it's not - when you graph this equation, it results in a v- kinda shape on the graph. Linear functions are [straight] lines on a graph, and this line wasn't straight. In fact, this wasn't even a line.
  3. No it's not - when you graph this equation, it results in a bend at the origin. The line on the graph is not straight, so this is not a linear equation.

For the graphs -

  • The first one represents the linear function [y = 4x - 7]
  • The second one (that looks like an L) represents the last not linear function [y = \frac{1}{2x} + 10]
  • The third one (that looks like a V) represents the first not linear function [y = 6x² - 1]

I HOPE THIS HELPS!

How do you find the derivative of 1/logx?
valentina_108 [34]

The derivative of 1/logx is With the chain rule.

1log(x)=log(x)−1 is ,= -1xlog(x)2 .

The by-product of logₐ x (log x with base a) is 1/(x ln a). Here, the thrilling issue is that we have "ln" withinside the by-product of "log x". Note that "ln" is referred to as the logarithm (or) it's miles a logarithm with base "e".

The by-product of 1/log x is -1/x(log x)^2. Note that 1/logx is the reciprocal of log.

With the chain rule. \\ 1log(x)=log(x)−1  \\ So you follow the chain rule to the electricity after which to the log: \\ ddxlog(x)−1=−1⋅log(x) \\  \\−2⋅ddxlog(x)  \\ =−1log(x)21x  \\ =−1xlog(x)2 .
