Determine the domain and range of (g ○ f)(x) if f of x is equal to 4 over the quantity x squared minus 4 end quantity and g(x) = x + 2. D: {x ∈ ℝ| x ≠ –2, 2} and R: (–∞, 1) ∪ (2, ∞)
D: {x ∈ ℝ| x ≠ –4, 0} and R: (–∞, –2) ∪ (2, ∞)
D: {x ∈ ℝ| x ≠ –4, –2, 0, 2} and R: (–∞, –1) ∪ (2, ∞)
D: {x ∈ ℝ} and R: (–∞, –2) ∪ (2, ∞)

step-by-step explanation:

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser

step-by-step explanation:

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
