The graph of g(x) is the graph of f(x)=x−2 reflected across the y-axis. which equation describes the function g? a. g(x)=−x−2 b. g(x)=−x+2 c. g(x)=x+2 d. g(x)=−2x+2

The equation that describes the function g(x) that is formed by reflecting the graph of f(x) = x - 2 across the y-axis is option A: g(x) = -x - 2

When the graph of a function f(x) is reflected across the y-axis to form g(x), then:

g(x)  =  f(-x)

The given function is:

f(x)  =  x  - 2

The graph of the function f(x)=x−2 reflected across the y-axis

g(x)  =  f(-x)

f(-x)  =  -x  -  2

Therefore,  g(x)  =  -x - 2

The equation that describes the function g(x) that is formed by reflecting the graph of f(x) = x - 2 across the y-axis is g(x) = -x - 2

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
