Answer:
f(3) = -20
Step-by-step explanation:
To find the value of a function, substitute the number for the variable and do the arithmetic.
f(x) = -2x^2 +x -5 . . . . . . given
f(3) = -2(3^2) +(3) -5 . . . . function value for x = 3
f(3) = -2(9) +3 -5 = -18 +3 -5
f(3) = -20
The absolute and relative cost difference in the restaurant and copycat meal are :
- Copycat meal is $4.20 less than restaurant meal
- Restaurant meal cost 1.88 times as much as copycat meal
- Copycat meal is 53% of the cost of restaurant meal
Cost of restaurant meal = $8.95
Cost of copycat version = $4.75

Percentage = (8.95 - 4.75) × 100% = 53.07% = 53%(nearest whole number)
The copycat meal is 53% of the cost of restaurant meal
Therefore, the relative and absolute cost difference are $4.20, 1.88 times and 53%
