Find the average rate of change of the parabola below over the interval [1,3]

Mathematics
1 answer:
weeeeeb [17]2 years ago
5 0

Answer:

D

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

\frac{f(b)-f(a)}{b-a}

Here (a, b ] = [ 1, 3 ], thus

f(b) = f(3) = 5 ← from graph

f(a) = f(1) = - 3 ← from graph

average rate of change = \frac{5-(-3)}{3-1} = \frac{8}{2} = 4 → D

Answer:  The answer to your first question would be A. 1.  This is simply because anything raised to the power of 0 is 1 no matter what.  The answer to your second question would be B. 1, for the same reason as above, anything to the power of 0 is 1.  Hope this helped and make sure to remember that rule, it is important and easy to remember!

M-N is M-N=2x^2+11x-9

Option B is correct.

Step-by-step explanation:

If M=5x^2+7x-4 and N=3x^2-4x+5 then find M-N

We need to subtract N from M

We will combine like terms (terms having same variable and exponent) and then solve them:

M=5x^2+7x-4

N=3x^2-4x+5

M-N=5x^2+7x-4-(3x^2-4x+5)\\M-N=5x^2+7x-4-3x^2+4x-5\\Combining\,\,like\,\,terms:\\M-N=5x^2-3x^2+7x+4x-4-5\\M-N=2x^2+11x-9

So, M-N is M-N=2x^2+11x-9

Option B is correct.
