The function f(x) has been transformed to give g(x). Which of the following functions represent g(x)
2 answers:
Answer:
Option A is correct.
Step-by-step explanation:
See the two graphs given in the diagram attached.
The first graph shows the function f(x) = x²
Hence, it passes through the points (1,1), (-1,1), (2,4) and (-2,4) points.
Now, from the plotted second graph we see the points (2,2), and (-2,2) are on the curve.
Hence, the y-value corresponding to the same x-value reduces by a factor in the second graph i.e. the graph of y = g(x) compared to the first graph.
So, we can conclude that the transformed graph has the equation .
Hence, option A is correct. (Answer)

According to the question,
-----(1)
-----(2)
multiplying (1) by 2 we get,
-----(3)
Deducting (2) from (3) we get,
⇒ ------------------(4)
Putting value of y in (1) we get,
⇒ ------------(5)
