10^{-x}=7^{4x}\\
\ln 10^{-x}=\ln 7^{4x}\\
-x \ln 10=4x\ln 7\\
-x \ln 10-4x\ln 7=0\\
x(-\ln 10-4\ln 7)=0\\
x=0

How to graph f(x)=(x-2)^2+3
iris [78.8K]

Using translation concepts, the graph of f(x) = (x - 2)² + 3 is given at the end of the question.

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

In this problem, we have that the parent and the translated function are given, respectively, by:

  • g(x) = x².
  • f(x) = (x - 2)² + 3.

The translations are as follows:

  • Right two units, as x -> x - 2.
  • Up 3 units, because f(x) = g(x) + 3.

Hence the graphs are given at the end of the answer, with the parent function in red and the translated function f(x) = (x - 2)² + 3 in green.
