Fantom [35]

Given:

The function is

f(x)=-3x^2+2x-7

To find:

The value of f(-1).

Solution:

We have,

f(x)=-3x^2+2x-7

Putting x=-1, we get

f(-1)=-3(-1)^2+2(-1)-7

f(-1)=-3(1)-2-7

f(-1)=-3-9

f(-1)=-12

Therefore, the value of f(-1) is -12.

Eka mixes 7 6 7 pints of grape juice and 3 1 5 pints of cranberry juice to make punch for a party. She has 5 pints of punch left
Sliva [168]

Answer:

Eka served about 1,047 pints of punch at the party

Step-by-step explanation:

Total pints of grape and cranberry juices mixed = 767 + 315 = 1052 pints

Number of pints left over = 5 pints

Number of pints served = (Number of pints mixed) - (Number left over)

Number of pints served = 1052 - 5 = 1,047 pints

Eka served about 1,047 pints of punch at the party
