Answer:

f(x)= \frac{7}{x}+10 and g(x)=x^2 

Step-by-step explanation:

Given : Equation y=\frac{7}{x^2}+10.

To find : f(x) and g(x) so the function can be expressed as y = f(g(x)) ?

Solution :

Our aim is to express f as a function of g, where g is a function itself, of x.

In the expression,

y= \frac{7}{x^{2}}+10

We may notice two functions, the squaring x function, which may well be our g i.e. g(x)=x^2 

The function is re-written as, y= \frac{7}{g(x)}+10

and the "7 divided by x, +10" function is  f(x)= \frac{7}{x}+10

Therefore, f(x)= \frac{7}{x}+10 and g(x)=x^2.

Given y = 7/x² + 10

Let,

y = f(x)

f(x) = 7/x² + 10

And,

g(x) = x²

Hence, f(g(x))

Reason is;
You have to rewrite f(x) so that it can fit in g(x) into the equation

f(x) = 7/g(x) + 10

I believe the fastest way to solve this problem is to take any two of the given points and to find the slope and y-intercept of the line connecting those two points.  

Let's choose the 2 given points (-3,16) and (-1,12).
Going from the first point to the second, the increase in x is 2 and the increase in y is actually a decrease:  -4.  Thus, the slope of the line connecting these two points is m = -4/2, or m = -2.

Now use the slope-intercept formula to find the y-intercept, b.

One point on the line is (-3,16), and the slope is m = -2.

Thus, the slope-intercept formula y = mx + b becomes 16 = -2(-3) + b.
Here, b comes out to 10.

So now we have the slope and the y-intercept.  Write the equation:

y = mx + b becomes y=-2x+10.  Which of the four given answer choices is the correct one?

Find a polynomial, which, when added to the polynomial 5x2–3x–9, is equivalent to: x2−5x+6
Bess [88]

The required polynomial is:-4x^2-2x+15

Step-by-step explanation:

Let P be the polynomial that has to be found

Given

One polynomial = 5x^2-3x-9

Sum of both polynomials = x^2-5x+6

So,

(5x^2-3x-9) + P = x^2-5x+6\\P = x^2-5x+6 - (5x^2-3x-9)\\P = x^2-5x+6-5x^2+3x+9\\P = x^2-5x^2-5x+3x+6+9\\P = -4x^2-2x+15

Hence,

The required polynomial is:-4x^2-2x+15
