Select the correct answer.
This table represents a quadratic function.
X= 1,3,5,7,9. Y=3,-3,-5,-3,3
Which statement about this function is true?
A.
The value of als negative, so the vertex Is a minimum.
B.
The value of a ls positive, so the vertex is a minimum.
C.
The value of a is positive, so the vertex is a maximum.
D.
The value of a is negative, so the vertex is a maximum.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1
