Answer:
B. The maximum occurs at the function's x-intercept.
Step-by-step explanation:
Given table:
From inspection of the table, we can see that:
and
This indicates <u>symmetry</u>.
The line of symmetry is the mid-point between the two x-values.
Therefore, the <u>line of symmetry</u> is x = -4
The vertex (minima/maxima) is on the line of symmetry, therefore the vertex is at (-4, 0). As the function decreases as x → 0, the vertex is a <u>maximum</u>.
As the y-value of the vertex is 0, the maximum occurs at the function's <u>x-intercept</u>.
Answer:
Y: 2
E: 9
A: 1
R: 0
Step-by-step explanation:
If we used the value Y = 2, E = 9 , A = 1 and R = 0
in the given equation i.e
.
From LHS,
Putting the value of Y,E, A and R in the given question we get
=RHS
