How do I do this question
exis [7]
To make the x the subject of an equation simply isolate x. To isolate means to get (something) by itself. To isolate x in this equation, just subtract A from both sides.

Note: Whatever operation you apply to an equation, you must apply to both sides of the equation to keep the sides equal. That is why you must subtract A from both sides.

      y = x + A
    -A        - A
y - A = x
      x = y - A

Answer:
x = y - A

Kahn Academy Question, Please help!
lara31 [8.8K]

g\circ f(-9)=g(f(-9))

By definition of f,

f(-9)=3\cdot9-8=19

and by definition of g,

g\circ f(-9)=g(f(-9))=g(19)=\sqrt{14-19}-10=\sqrt{-5}-10

which is undefined if f,g are supposed to be real-valued functions. If they're complex-valued, then \sqrt{-5}=i\sqrt 5 and g\circ f(-9)=-10+i\sqrt 5.
