Which function is a quadratic function? O ux)=-X+3x2-8
V)=2x?+8x3+ 9x
O y) = x+3x5+4
O z(x)= 7x2+2-3

The answer is actually A.) u(x)= -x + 3x^2 - 8

step-by-step explanation:

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.
