Answer:
Explanation:
Checking if the coordinates of the supplied points fulfil the respective functions is necessary to identify which of the given points lies on the graphs of the functions f(x) = (2x + 4) and g(x) = x3 + 4.
1. Point (1.9, 2.8):
For f(x) = f(2x + 4): f(1.9) = f(2 * 1.9 + 4) f(3.8 + 4) f(7.8 + 4) f(3.8 + 4) f(7.8 + 4) f(3.8 + 4) f(7.8 + 4) f(3.8 + 4) f(7.8 + 4) f(3.8 + 4) f(7.8 + 4)
Since the point's y-coordinate is 2.8, it does not quite lie on the f(x) graph.
G(1.9) = 1.93 - 4 6.859 (rounded to three decimal places) for the expression g(x) = x3 - 4
Since the point's y-coordinate is 2.8, it does not quite lie on the g(x) graph.
2. Point (-1.3, 2.9):
F(-1.3) = ((2 * (-1.3) + 4) for f(x) = ((2x + 4) (2.6 + 4) 6.6 2.57 (rounded to two decimal places)
3. Point(0,2) we not having it is
So the answer is (1.6,0)
