1 answer:
The error in the process is we have to add the coordinates john subtracts the coordinates.
The transformation coordinates are (8, 12).
Given that
John says the transformation rule (x, y) Right-arrow (x 4, y 7) can be used to describe the slide of the pre-image (4, 5) to the image (0, –2).
We have to determine
What was his error?
According to the question
A preimage or an inverse image is the 2D shape that we used to denote before any transformation.
Image is the figure that we get after transformation.
The coordinates of preimages are (4, 5).
Then,
After transformation the co-ordinates are as follows;
Hence, the transformation coordinates are (8, 12).

Step-by-step explanation:
It helps a lot to draw a triangle. Sin is OPPOSITE/ HYPOTENUSE. You can use Pythagorean thm to find the third side. Then use cos = ADJ/HYP
tan = OPP/HYP
Then, find reciprocal functions. Reciprocal just means you are flipping the ratios over.
csc = HYP/OPP
sec = HYP/ADJ
tan = ADJ/OPP
The only tricky remaining part is that you cant leave a radical (the square root symbol) on the bottom of a ratio. So you have to fix those. See image.
f(x)=x²-1
g(x)=2x-3
f(x)*g(x)=(x²-1)*(2x-3)-----------> <span>this function exists for all real numbers</span>
the answer is the interval (-∞,∞)
