Sagot :

Answer:

1. y=(x-1)(2x+3)(x-4)

x-intercept: 0=(x-1)(2x+3)(x-4)

x-1=0

2x+3=0

x-4=0

[(1,0),(-3/2,0),(4,0,)]

y-intercept: y=(0-1)(2(0)+3)(0-4)

y=(-1)(3)(-4)

[(0,12)]

2. y= -(x+1)² (x-2)²

x-intercept: 0= -(x+1)² (x-2)²

(x+1)²=0

(x-2)²=0

[(-1,0),(2,0)]

y-intercept: y= -(0+1)² (0-2)²

y= -(1)(4)

[(0,-4)]

3. y=x(x-1)(x-2)(x+3)

x-intercept: 0=x(x-1)(x-2)(x+3)

x=0

x-1=0

x-2=0

x+3=0

[(0,0),(1,0),(2,0),(-3,0)]

y-intercept: y=0(0-1)(0-2)(0+3)

[(0,0)]

4. y= -(x+3)(x-2)(x-4)(x+1)

x-intercept: 0= -(x+3)(x-2)(x-4)(x+1)

x+3=0

x-2=0

x-4=0

x+1=0

[(-3,0),(2,0),(4,0),(-1,0)]

y-intercept: y=-(0+3)(0-2)(0-4)(0+1)

y=-(3)(-2)(-4)(1)

[(0,-24)]

5. y=(x+1)(x-1)(x+5)(x-5)

x-intercept: 0=(x+1)(x-1)(x+5)(x-5)

x±1=0

x±5=0

[(1,0),(-1,0),(5,0),(-5,0)]

y-intercept: y=(0+1)(0-1)(0+5)(0-5)

y=(1)(-1)(5)(-5)

[(0,25)]
