tan(2θ)−sec2(θ)−sec(θ)

Step-by-step explanation: Simplify Each Term

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

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
