We have to compute: Δ y / Δ x.
The interval is [ 2, 5 ] and y = 4 x - 9.
y 1 = 4 · 2 - 9 = 8 - 9 = - 1
y 2 = 4 · 5 - 9 = 20 - 9 = 11
Δ y / Δ x = ( y 2 - y 1 ) / ( x 2 - x 1 ) =
= ( 11 - ( - 1 ) ) / ( 5 - 2 ) = ( 11 + 1 ) / 3 = 12 / 3 = 4
Answer:
Δ y / Δ x = 4

Answer: odd

Step-by-step explanation:

Given

The graph of a function increases as x increases and decreases as x decreases.

This shows that the degree of the polynomial is odd

for example y=x^3

Here, the leading coefficient is positive, and the value of function increases as x increases and vice-versa.
