1. y=5x³- x+2
2. P(x)=x² + 2x -1

how do these mathematical statement differ from polynomial expressions?​


Sagot :

Answer:

1. y=5x³- x+2

Substitute x = 0

y=5(0)³ - (0)+2

Solve the equation

y=2

2. P(x)=x² + 2x -1

Substitute x = 0

p(0)=(0)²+2(0)-1

Evaluate the power and multiply

p(0)=0+0-1

Remove zeros

p(0)=-1

I used the formula in finding the y-intercept
