cupoosta [38]

Answer:

Step-by-step explanation:

Solution

When, x=2

f(2)=3×2+8

=14

Again,

When, x=1

f(1)=3×1+8

=11

When, x=0

f(0)=3×0+8

=8

When, x=-1

f(-1)= 3×(-1)+8

=5

Answer:

Step-by-step explanation:

x-4=0

x=4

i solve by synthetic division.

4| 1 -7 14 -8

| 4 -12 8

___________

| 1 -3 2 | 0

$x^3-7x^2+14x-8=(x-4)(x2-3x+2)\\=(x-4)[x^2-x-2x+2]\\=(x-4)[x(x-1)-2(x-1)]\\=(x-4)(x-1)(x-2)$

x-intercepts are (4,0),(1,0),(2,0)

put x=0

y=-8

y -intercept is (0,-8)
