Could really use some y'all-

for the function below, find f(2):

f(x)=2x^4-8x^2+5x-7

a. f(2)= 3

b. f(2)= -2

c. f(2)= -13

d. f(2)= 0

    Ok you just replace the x for a 2.

2(2)^4 - 8(2)^2 + 5(2) - 7

2(16) - 8(4) + 5(2) - 7

32 - 32 + 10 - 7

10 - 7

3

It's A. f(2) = 3.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
