AABC is reflected across the x-axis and then translated 4 units up to create AA'BC. What are the coordinates of the vertices of AABC? A. A'(-3, 3), B(-1, 1). C(-2.3)
В. A'(3.-3), B(1,-1), C(2.-3)
C. A'(3.-5), B(1, -7), C(3.-5)
D. A'(-3, 3), B(-1, 1), C(-2,-3)

the answer is 48m^2!

step-by-step explanation:

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex
