Given:
The figure of a triangle DEF.
To find:
The coordinate of image of given triangle after reflection over y-axis.
Solution:
The vertices of given triangle are D(1,4), E(4,3), F(2,0).
If a figure is reflected over the y-axis, then the rule of reflection is

Using this rule, we get



Therefore, the coordinates of image are D'(-1,4), E'(-4,3) and F'(-2,0).

Answer:
The answer is C/85,000
Step-by-step explanation:
a. (f+g)(x) = 8x+2
b. (f-g)(x) = 4x-6
Step-by-step explanation:
Given

<u>a. (f+g)(x)</u>

<u>b. (f-g)(x)</u>

Hence,
a. (f+g)(x) = 8x+2
b. (f-g)(x) = 4x-6
