What is it’s determinant?
does the determinant depend on the variables?
make a conjecture.

det = 8

Step-by-step explanation:

1(8 - 0) - x(0 - 0) + y(0 - 0)

= 8

The determinant is 8. The determinant does not depend on the variables in the matrix. When there are zeros below the main diagonal, the determinant is the product of the diagonal.

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
