Answer:

Choice B is correct answer.

Step-by-step explanation:

We have given two functions.

f(x) = 3x+1    and g(x) = x²-6

We have to find the sum of given two functions.

(f+g)(x) = ?

The formula to find the sum of two functions:

(f+g)(x) = f(x) + g(x)

Putting the given values of functions , we have

(f+g)(x) = 3x+1 + x²-6

Adding like terms , we have

(f+g)(x) = 3x+x²-5

Rearranging, we have

(f+g)(x) = x²+3x-5  which is the answer.

Answer:

option B is correct, i.e. (f+g)(x) = x² + 3x - 5.

Step-by-step explanation:

Given f(x) = 3x + 1.

Given g(x) = x² - 6.

To find (f+g)(x).

The rule of Arithmetic of functions is:- (f+g)(x) = f(x) + g(x).

(f+g)(x) = (3x+1) + (x²-6).

(f+g)(x) = x² + 3x + 1 - 6.

(f+g)(x) = x² + 3x - 5.

Hence, option B is correct, i.e. (f+g)(x) = x² + 3x - 5.

Given f(x) = x^2 + 2 and g(x) = 2 – x, find a simplified expression for f(2x) + g(3x).
Blababa [14]

Answer:

f(2)+g(3) = 5

Step-by-step explanation:

Given that,

f(x) = x² + 2

g(x) = 2-x

We need to find the value of f(2)+g(3).

f(2) = 2² + 2 = 6

g(3) = 2 – 3 = -1

So,

f(2)+g(3) = 6+(-1)

= 5

Hence, the value of the given expression is 5.

What is the x-intercepts of the graph of y = 12x-5x-2
hammer [34]
Y = 12x - 5x - 2

first simplify the equation by subtracting like terms (in this case):

12x - 5x = 7x

y = 7x - 2

Since you are finding the x, you must isolate the x. Do the opposite of PEMDAS.(Note: because there is a equal sign, what you do to one side, you do to the other)

y = 7x - 2

y (+2) = 7x - 2 (+2)
y + 2 = 7x
(y + 2)/7 = 7x/7

x = (y + 2)/7


x = (y + 2)/7 is your answer

hope this helps
