An illustration of the letter 'A' in a speech bubbles

The point (2, 3) is on the graph of y =f(x). The corresponding coordinates of this point on the graph of `y = -2*(f(2(x+5)) - 4` has to be determined.

Let the required coordinates be (x', y')

x' = 2(x+5)

=> x' = 2x + 10

Substituting x = 2,...

The point (2, 3) is on the graph of y =f(x). The corresponding coordinates of this point on the graph of `y = -2*(f(2(x+5)) - 4` has to be determined.

Let the required coordinates be (x', y')

x' = 2(x+5)

=> x' = 2x + 10

Substituting x = 2, x' = 14

y' = -2*3 - 4 = -10

The coordinates of the point on the graph of `y = -2*(f(2(x+5)) - 4` that correspond to the point (2, 3) is on the graph of `y =f(x)` is (14, -10)
