Answer:
b. because m = -5
Step-by-step explanation:
y = -5x +9
m (gradient) is the coefficient before the 'x' term
Answer:
d
Step-by-step explanation:
Your overall grade will go down. I'd try to ask your teacher if you can make them up.
Answer:
(d) f(x) = (x − 3)^2(x − 2)(x − 1)
Step-by-step explanation:
In this context, a crossing of the axis at x=p means there is a factor of (x-p). A "touch" of the axis at x=q means there is a factor of (x -q)^2.
A crossing at x=1 and x=2, and a touch at x=3 means the factors are ...
f(x) = (x -1)(x -2)(x -3)^2 . . . . . matches the last choice
