it is a polynomial and the degree is 6
Step-by-step explanation:
a polynomial is a function which involves positive integral powers
That is if the exponents are positive integers
Answer:
D
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is

Here [ a, b ] = [ 2, 4 ]
From the table
f(b) = f(4) = 16
f(a) = f(2) = 4, hence
average rate of change =
=
= 6
Answer:
y = 2(x +1)(x -4)
Step-by-step explanation:
The intercepts are at grid points, so it is easiest to make use of those. For an x-intercept of "a", one of the factors of the function is (x -a). Here, the x-intercepts are -1 and +4, so the function has factors (x +1)(x -4).
When x=0, the product of these factors is (1)(-4) = -4, so there is a vertical scale factor of 2 to make the y-intercept be -8. The function can be written as ...
y = 2(x +1)(x -4)
Answer:
66
Step-by-step explanation:
11 - 9 + 8^2
11 - 9 + 64
= 66
Answer:
A town with 600 people need 10 firefighters
A town with 1500 people will need 1500 x 10/600 = 1500/60
= 25 firefighters
Hope this helps!
