Solving the inverses of these functions and applying the composite we obtain:
(G⁻¹ о F⁻¹) = X
Note that (F⁻¹ о G⁻¹) also results in X (see second annex)
Plug in 2 for your x, you'll get 2(2^2)+3, which becomes 2(4)+3, 8+3, 11.
Answer:
z=70, y=102
Step-by-step explanation:
180-110 = 70
so, z=70
99+89+70 = 258
360-258 = 102
so, y=102
