Solution:
As we are given that f(1) = 0 .
It mean that is one of the factor of the given equation.
Remainder theorem can be applied as below:
Hence the factors are (x-1),(x+3) and (x+1).
Hence the correct option is B.
Answer:
A, C, E
Step-by-step explanation:
From the table you can see that the water depth cahnges
for every
of snow (option B is false).
This means that the function modelling this situation is linear function (option A is true and option D is false). Let the equation of this function be Then
Subtract these two equations:
Hence,
The equation of the straight line (the graph of linear function) is (option E is true) This line passes through the point (0,0), because its coordinates satisfy the equation (option C is true).
