Take two points
(-3, -1) and (1,2)
Find slope
slope formula: m = y2 - y1 / x2 - x1
m = 2 - (-1) / 1 - (-3) = 2 + 1 / 1 + 3 = 3/4
Substitute one of the points into slope intercept form (y =mx + b) to find the y intercept.

y= mx + b
2 = 3/4(1) + b
2 = 3/4 + b
1.25 = b

So:
y = 3/4x + 1.25

liubo4ka [24]

Answer:

f(x) has three real roots and two imaginary roots.

Step-by-step explanation:

Given that three roots of a fifth degree polynomial function f(x) are -2,2 and (4+i).

Now we need to find about which of the given statements describes the number and nature of all roots for this function.

We know that imaginary roots always occur in conjugate pairs.

So if (4+i) is root then (4-i) must also be the root.

So now we have total 4 roots

-2, 2, (4+i) and (4-i).

Degree of the polynomial is 5 so that means 1 root is still remaining. It can't be imaginary as that must be in pairs

So that means 5th root is real.

Hence correct choice is :

f(x) has three real roots and two imaginary roots.

=6(24x³-9x²-56x+21)

=6(3x²x(8x-3)-7(8x-3))

=6(8x-3)x(3x²-7)
