Select all of the following that are ordered pairs of the given function. h(x) = 3x2

Answer with explanation:

 The given function is

h(x)=3 x²(1)

We have to find those ordered pairs ,(1, 3) ,(−1, −3) ,(−1, 3) ,(1, −3) which satisfy the given function.

Substituting , different value of x,in equation 1 , to find correct ordered pairs.

1.

h(1)=3 × 1²=3×1=3

Ordered pair, (1,3) satisfy the given function.

2.

h(-1)=3 × (-1)²

      =3 × 1

     =3

Ordered pair, (-1,3) satisfy the given function.

Option A →(1,3) and C,→ (-1,3)

y > 1/3x

y < = -x + 4

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
