Every function is a relation. However, not every relation is a function. In a function, there cannot be two lists that disagree on only the last element.

Hope this helps :)

Every function is a relation, but not every relation is a function.

Hope this helps :)

Hey there!

If the tallest trophy is about 270 inches, and you stack 4 of those trophies on top of each other, you'd be multiplying 270 times 4.

270×4= 1,080

So, if you stacked four 270-inch trophies on top of each other, they would be 1,080 inches high.

HELP! (WILL MARK BRAINLIEST!)

givi [52]

Step-by-step explanation:

Step 1: Identify the blanks

$f(x) = \sqrt{x-3}$ and $g(x) = 2x + 4$

f · g = $f( g( x ) )$

= $f( 2x + 4 )$

= $\sqrt{(2x + 4) - 3}$

= $\sqrt{2x + 1}$

Since the g(x) is in the inside, that is what goes in first to produce the f(2x + 4). Now we put in (2x + 4) into the x of the f(x) function.

This produces: $\sqrt{(2x + 4) - 3}$

Now, we just combine like terms to get: $\sqrt{2x + 1}$

What is the solution of [2x 3]=7?

Vsevolod [243]

Well solve for x by simplifying both sides the isolating the variable to get x=5 for 2x-3 or x=2 for 2x+3
