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
∵
∵
∵ 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

<em>The red line represents h(x)</em>
<em>The blue line represents m(x)</em>
