What is the product?<br> (-2x- 9y2 )(-4x-3)

lara [203]

Answer:

$36xy^2 + 8x^2 + 27y^2 + 6x$

Step-by-step explanation:

Use the FOIL method of multiplying binomials.

First term in each binomial: $-2x * -4x = 8x^2$

Outside terms: $-2x * -3 = 6x$

Inside terms: $-9y^2 * -4x = 36xy^2$

Last term in each binomial: $-9y^2 * -3 = 27y^2$

Now, rearrange the terms correctly. $36xy^2 + 8x^2 + 27y^2 + 6x$

This is our final answer, since it can not be simplified any more.

Think about the function f(x) = 3 - 2x. What does the notation f(0) mean? f(0) = What is the special name of f(0)?

mel-nik [20]

Notation f(0) means the graph crosses y-axis where x becomes zero

or simply y-intercept

f(x) = 3 - 2x

put x = 0

f(0) = 3 - 2(0)

f(0) = 3 - 0

f(0) = 3

Special name of f(0) : <em>y-intercept</em>
