What does (fog)(x) mean?

2 answers:

8 0

(fog)(x) means f(g(x)). this means we have to use the two functions f(x) and g(x). In this case, we substitute the function of g(x) to the x- variable of the function of f(x). The two functions can be both polynomials or monomials. In this case, the answer to this problem is f(g(x)).

Lf g(x) = x3 - 5 and h(x) = 2x - 2, find g(h(3)).

White raven [17]

Answer: g(h(3)) = 59

Step-by-step explanation:

Well if its x^3 I assume it is because you wrote other coefficients before the variable.

2(3) - 2 = 6-2 = 4

So 4 is the x input for h(x)

4^3 -5 = 64-5 = 59

I JUST REALLY MEED HELP I GIVE BRAINLIEST

Nutka1998 [239]

Answer:

32 dollars

Step-by-step explanation:

Let's say the original price is x

Create an equation:

$\frac{1}{2}x -5 = 11$

Add 5 on both sides

$\frac{1}{2}x = 16$

x = 32

The answer is 32 dollars

Hope this helps :)

-1/3x+2x=3 3/4 what does the variable represent?

svet-max [94.6K]

Start off by combining like terms on the LHS (the terms with x in them).

So we get $\frac{-1}{3}x+2x= \frac{-1}{3}x+ \frac{6}{3}x= \frac{-5}{3}x$

Replacing this result with what we had before on the LHS, we get $\frac{-5}{3}x=3 \frac{3}{4}= \frac{9}{4}$

⇒Solve for x (divide both sides $\frac{-5}{3}$ )
⇒Don't forget about reciprocity rules when dividing. This is the same as multiplying both sides by $\frac{3}{-5}$

⇒ $x= \frac{9}{4}( \frac{3}{-5})
$
⇒ $x= -\frac{27}{20}=-1\frac{7}{20}$ ***This is a proper fraction
