Answer:

B

Step-by-step explanation:

Plug in a x-value and see which table matches the result.  Plug in 1.

f(x) = 7 - 4.5x

f(1) = 7 - 4.5(1)

f(1) = 7 - 4.5

f(1) = 2.5

The table that matches an input of 1 with an output of 2.5 is B.

Compare and Contrast how you would factor x^2−9 and x^2+9. For full credit, make sure you explain why they are factored differen
marishachu [46]

The factored form of the expression x^2 - 9 is (x+3)(x-3)

The expression x^2 + 9 has no real roots hence cannot be factored

Quadratic equations are equations with a degree of 2.

Given the quadratic function x^2-9 \ and \ x^2+9

For the function x^2 - 9

=x^2-9\\=x^2-3^2

Using the difference of two squares:

a^2-b^2=(a-b)(a+b)\\x^2-3^2=(x-3)(x+3)

For the expression x^2 + 9

The expression x^2 + 9 has no real roots hence cannot be factored
