Step-by-step explanation:
Using the rules of exponents
⇔
and
= 1
Substitute the values of x into 
x = 0 →
= 1 ⇒ a = 1
x = 2 →
=
=
, hence
b = 
x = 4 →
=
=
, hence
c = 
Answer:
y = -3x-1
Step-by-step explanation:
all u had to do was plug it into y = mx+b
If you have a graphing calculator just put in the equation in 'y=' (not the i equation), and then go to 2nd trace and see where the y=0, those numbers under the x column are the zeros.
