Please help me with this math question, I'm so confused, I will mark you brainliest

A) 2

B) 3

C) -2

D) -1

Step-by-step explanation:

All you need to do is trace the given X value to the graph of the function after 'o' in (fog) or (gof). This is the same as finding the value of f(x) or g(x). After finding the value, make that value your x and trace to the new value on the other graph

a) Tracing -1 to y = f(X) gives y= 3. Tracing x =3 to g(x) gives 2

step-by-step explanation:

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
