The graph of f (in blue) is translated a whole number of units horizontally and vertically to obtain the graph of h(in red).

The function f is defined by f(x) = square root of x

Write down the expression for h(x).

h(x) = square root of (x-2) +4

Answer:

\(h(x)=\sqrt{x-2}+4\)

Step-by-step explanation:

Initially the graph f (x) is shifted horizontally to the right.

When the graph shifts to right the function then becomes

f(x)→f(x-b)

Where b is the units by which it is shifted towards right .

So, in the figure we can see that it is shifted 2 units to the right .

So, f(x)→f(x-2)

Since f(x) is \(\sqrt{x}\)

So, f(x-2) =  \(\sqrt{x-2}\)

Now the new obtained graph is again shifted vertically upward

When the graphs shifts upward f(x) →f(x)+b

where b is the units by which it is shifted upward

So, our obtained f(x-2)  when shifted upward by 4 units so using the above given transformation of upward shift i.e. f(x) →f(x)+b

So,   Our new graph h(x) = f(x-2)+4

⇒  \(h(x)=\sqrt{x-2}+4\)
