What is the coefficient in the expression 5x2 ?

5

x

x2

The middle term is, -5x 2 its coefficient is -5 . The last term, "the constant", is -2 Step-1 : Multiply the coefficient of the first term by the constant 3 • -2 = -6

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
