The graph of which function will have a maximum and a y-intercept of 4?
f(x) = 4x2 + 6x - 1
f(x) = -4x2 + 8x + 5
f(x) = -x2 + 2x + 4
O Ax) = x² + 4x - 4

there are no figures how am i supposed to answer this question

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.

y > 1/3x

y < = -x + 4

hope this : )
