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)

Answer:
B
Step-by-step explanation:
The figure is a trapezium with area (A) calculated as
A = h (a + b)
where h is the perpendicular height and a, b the parallel bases
Here h = 8, a = 10 and b = 6, thus
A = × 8 × (10 + 6) = 4 × 16 = 64 cm² → B
