Answer:
Up 1 and over 3
Step-by-step explanation:
This can be determined by finding the x-intercept. In doing so, we let y=0 to find the value of x.
y= 2x^2 -x -3
[0 = 2x^2 -x-3]÷2
0 = x^2 -1/2 x - 3/2
Complete the squares:
1/16 + 3/2 = x^2 - 1/2x + 1/16
25/16 = (x -1/4)^2
sqrt (25/16) = x - 1/4
+/- 5/4 = x - 1/4
Thus,
x = 1/4 + 5/4 = 3/2
x = 1/4 - 5/4 = -1
Thus, the graph crosses at x = 3/2 and x = -1.
Answer:
A all numbers less than 250
Step-by-step explanation:
Not sure is fully correct tho sorry
Answer:
D.
Step-by-step explanation:
That would be D because there is a repetition of x = -6.
-6 maps to -6, 5 and -5 which is not allowed in a function.
Functions can be one-to-one or many-to-one but not one-to-many.
