2. Find the remainder in each of the following when f(x) is divided by d(x), by using remainder theorem: (a) f(x) = x3 + 3x2 + 9x - 7 d(x) = x - 2
(b) f(x) = x3 + 4x2 - 7x - 20 d(x) = x - 4
(c) f(x) = 2x3 + 3x2 - 8x + 50 d(x) = x + 3
(d) f(x) = x3 + 4x2 - 20x + 20 d(x) = x + 2
(e) f(x) = 2x3 + 4x2 - 10x + 20 d(x) = 2x - 1
(f) f(x) = 16x3 + 12x2 + 24x + 5 d(x) = 2x + 3

it's a optional mathematics Questions please solve him​

nope.   happens to me as well.

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
