Answer:
b(x)
Step-by-step explanation:
From the table for a(x)
The y- intercept where x = 0 is 2
For b(x) the curve crosses the y- axis at y = 3 ← y- intercept
c(x) = [tex](\frac{1}{2}) ^{x}[/tex] - 1
To find the y- intercept let x = 0 , then
f(0) = [tex](\frac{1}{2}) ^{0}[/tex] - 1 = 1 - 1 = 0 ← y- intercept
The graph of d(x) crosses the y- axis at (0, - 4 )
Then y- intercept = - 4
The largest y- intercept is 3 , that is b(x)
