If f(x)

Mathematics
2 answers:

6 0

Step-by-step explanation:

Hey there!

Given function is f(X) = 11x+7.

Let f(X) be y.

So, y = 11x+7

Interchanging"X" and "y" we get;

X = 11y+7

or, X-7 = 11y

or, y = (x-7)/11

Therefore {f}^{ - 1} (x) = \frac{x - 7}{11} [/tex]

<u>Hope</u><u> </u><u>it </u><u>helps</u><u>!</u>

Answer: f^-1(x) = (y - 7)/11

Explanation:
f(x) = 11x + 7
y = 11x + 7
y - 7 = 11x
(y - 7)/11 = x

Let f (x)=x-2 and g(x)=x to the second power -7x-9.find f (g(-1))
Degger [83]

f(g(-1)) = - 3

Evaluate g(-1) and substitute into f(x)

g(-1) = (-1)² -7(-1) - 9 = 1 + 7 - 9 = - 1

f(g(-1)) = (-1) - 2 = - 3

For a science experiment Ella recorded the time, in seconds, to boil 650 grams of solution. Her results were 24.5, 23.2, 29.8, a
bagirrra123 [75]

Answer:

Mean of boiling times = 26.9 seconds

Step-by-step explanation:

Times ella recorded are given as;

24.5 seconds, 23.2 seconds, 29.8 seconds, and 30.1 seconds.

Now, we want to find the mean of these boiling times.

Formula for mean is;

Mean = sum of terms/number of terms

In this question,

number of terms = 4

Sum of terms = 24.5 + 23.2 + 29.8 + 30.1 = 107.6

Thus,

Mean = 107.6/4

Mean = 26.9 seconds

If f(x) = (x^1/2 - x)
Slav-nsk [51]
Well, you are subtracting g(x) from f(x) so:

√x-x-(2x^3-√x-x) which is:

√x-x-2x^3+√x+x  (you have your signs wrong at the bottom of your post)

Now you would simply combine like terms (do your addition and subtraction of like terms)

-2x^3+2√x

So the answer is D.
