Answer:
2.64
Step-by-step explanation:
0.9(x + 1.4) - 2.3 + 0.1x = 1.6
0.9x + 1.26 -2.3 + 0.1x - 1.6 = 0
(0.9x + 0.1x) + (1.26 - 2.3 - 1.6) = 0
x - 2.64 = 0
x = 2.64
Step-by-step explanation:
Domain x belongs to [-4 , 0]
Range y belongs to [-4 , 4]
The third one is the answer
I guess the original function was
y = 5x (1)
y+Δy =5(x+Δx) (2)
(2) - (1) =
Δy = 5Δx
Δx →0, Δy/Δx →5
