Answer:
b) x^4 varies directly as y
is the right answer
Step-by-step explanation:
Given that x and y are related by the equation
This can be rewritten as
If x^4 =z is substituted we have
z=7y
i.e. Z directly varies as y and constant of proportionality is 7.
Hence we can write
x^4 varies directly as y
Option b is right
Go from -2 to zero. Then zero to 3. Think of a line and zero is the middle. It goes 2 to the left and 3 to the right. So, 5 total number of units.
