Translate each point of the graph of h(x) 3 units left.

Answer 1

Answer:

Translate each point of the graph of h(x) 3 units left ⇒ 4th answer

Step-by-step explanation:

Let us revise the translation of a graph

• If the function f(x) translated horizontally to the right by h units, then its image is g(x) = f(x - h)  
• If the function f(x) translated horizontally to the left by h units, then its image is g(x) = f(x + h)  
• If the function f(x) translated vertically up by k units, then its image is g(x) = f(x) + k  
• If the function f(x) translated vertically down by k units, then its image is g(x) = f(x) - k  

∵ $h(x)=log_{6}(x)$

∵  $m(x)=log_{6}(x+3)$

∵ x in h(x) is changed to (x + 3) in m(x)

- From the 2nd rule above, that means the graph of h(x)

   is translated 3 units to the left

∴ The graph of h(x) is translated 3 units to the left

∴ Each point on the graph of h(x) is translated 3 units to the left

∴ Translate each point of the graph of h(x) 3 units left
