1. you didn't add anything
2. x>-4
g(x), h(x), f(x)
f(x), h(x), g(x)
g(x), f(x), h(x)
h(x), f(x), g(x)
Answer:
Huh? what do you mean?
Step-by-step explanation:
Hello, there!
<span>This is already simplified as there are no like terms that can be combined. x^3 is different than x^2, so it can't be combined.
x^3 is different from y^2 so it can't be combined.
And finally, x^2 is different from y^2, so it can't be combined either.

I hope I helped!
Let me know if you need anything else!

y = 20x
The graph passes through the origin , hence is of form
y = mx ( m is the slope )
to calculate m use the gradient formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁) = (2, 40) and (x₂, y₂) = (4, 80) ← 2 points on the graph
m = 
= 
= 20
y = 20x
