First plug in (x+h) for x in the function.
f(x+h)= 2(x-h)^2-3(x-h) = 2(x^2-2xh+h^2)-3x-3h =
2x^2-4xh+2h^2-3x-3h - 2x^2 +3x =
(-4xh +2h^2-3h)/h
-4x +2h-3

Dallison cooked a 5-pound roast for supper. What is the estimate mass in grams

Lisa [10]

Answer:

Estimated mass of cooked food is 2267.96185 grams

Step-by-step explanation:

The total dinner cooked = 5 pounds

Now by the Parametric Conversion, we know that

1 pound = 453.59237 grams

So, converting the total mass of food in grams, we get

5 pound roast = 5 x 453.59237 grams roast

= 2267.96185 grams

⇒ 5 Pounds = 2267.96185 grams

So, estimated mass of cooked food is 2267.96185 grams.
