Answer:

d. The mapping represents y as a function of x, because each x-value corresponds to exactly one y-value.

Step-by-step explanation:

This would be a function as long as one x-value doesn't correspond to two y-values. If two x-values correspond to one y-value though, it still represents a function.

ANSWER

two inputs can have the same output but two different outputs can't have the same input so this does represent a function and is therefore D

lions [1.4K]

Step-by-step explanation:

4h+6h2+1−(5h2−8h4+6)

=4h+6h2+1+−1(5h2−8h4+6)

=4h+6h2+1+−1(5h2)+−1(−8h4)+(−1)(6)

=4h+6h2+1+−5h2+8h4+−6

=(8h4)+(6h2+−5h2)+(4h)+(1+−6)

=8h4+h2+4h+−5 <- Answer

Factor each.<br><br><br> Please help!

Answer:

1) The factors of $x^2-3x+2=0$ are $\mathbf{(x-1)(x-2)=0}$

Option C is correct.

3) The factors of $x^2+2x-8=0$ are $\mathbf{(x-2)(x+4)=0}$

Option B is correct.

Step-by-step explanation:

1) Factor : $x^2-3x+2=0$

For factoring we need to break the middle term, such that there sum is equal to middle term of expression and product is equal to product of first and last term.

The middle term : -3x

We can break them as (-2x)( -x)

Solving:

$x^2-3x+2=0\\x^2-2x-x+2=0\\x(x-2)-1(x-2)=0\\(x-1)(x-2)=0$

So, factors of $x^2-3x+2=0$ are $\mathbf{(x-1)(x-2)=0}$

Option C is correct.

3) Factor: $x^2+2x-8=0$

For factoring we need to break the middle term, such that there sum is equal to middle term of expression and product is equal to product of first and last term.

The middle term : 2x

We can break them as (4x)( -2x)

Solving

$x^2+2x-8=0\\x^2+4x-2x-8=0\\x(x+4)-2(x+4)=0\\(x-2)(x+4)=0$

So, factors of $x^2+2x-8=0$ are $\mathbf{(x-2)(x+4)=0}$

Option B is correct.
