The relation of this set of points is a function. True or false.

1 answer:

4 0

Just graph it... Firstly though, do you know what a function is?
Google linear function, parabolic function, exponential function etc. to get familiar with what a function looks like.

Firstly, no function that I know has
(4, 5) and (4, -4) where there are two y coordinates for 1 x coordinate.
It is not linear, parabolic, or exponential, it could be some other type of function. But assuming you're in high school i'd say its safe to bet the answer is FALSE.

F(x)=3x square + x f(-5)

KatRina [158]

Answer:

If you need the answer as f by simplifying both sides of the equation and then isolating the variable, the answer would be:

$xf=\frac{3x^2}{5}-\frac{f(x)}{5}$

Or, if you need to evaluate the function itself, the answer would be:

$f(x)=3x^2-5xf$

Which expression is a simplified form of –10g – 4h^2 + 15g – 8h^2 – 4?

igomit [66]

Hi there!

»»————-　★　————-««

I believe your answer is:

$-12h^2+ 5g-4$

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

$-10g -4h^2+15g-8h^2-4\\------------------\\\rightarrow -10g+15g -4h^2-8h^2-4\\\\\rightarrow 5g - 12h^2 - 4\\\\\rightarrow \boxed{-12h^2+5g-4}$

⸻⸻⸻⸻

Which expression can be used to find the surface area of the following square pyramid?

telo118 [61]

Answer:

Step-by-step explanation:

The slant height of one side of this pyramid is 5, and the base of this side is 4. Thus, the area of one slant side is (1/2)(5)(4) = 10 units^2.

There are 4 such sides. Thus, the total slant surface area is 4(10 units^2), or 40 units^2.

If you also want to include the base area, the total would be

40 units^2 + 16 units^2 = 56 units^2.
