Answer: x < -5 1/2 or x < -11/2
Step-by-step explanation:
2 ( 4x + 1 ) < 3 ( 2x - 3 )
8x + 2 < 6x - 9
8x - 6x < -9 -2
2x < -11
x < -11/2
x < -5 1/2
Answer:
x^2-4x+3
Step-by-step explanation:
Since the zeroes of the quadratic are 1 and 3, we can set up an equation in factored form:
(x-1)(x-3)
=x^2-4x+3
We can further check that this is the right answer by evaluating it at the vertex:
(2)^2-4*2+3=-1
Since that corresponds to the graph, the answer is x^2-4x+3
