One root of f(x)=x^3-4x^2-20x+48 is x = 6. what are all the factors of the function? use the remainder theorem.

a.(x + 6)(x + 8)
b.(x – 6)(x – 8)
c.(x – 2)(x + 4)(x – 6)
d.(x + 2)(x – 4)(x + 6)

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
