Let f(x) = 3x² + 1 and g(x) = x +4. <br><br> Find (f +g)(x) <br><br> and (f -g)(x).
Artist 52 [7]

Answer:

(f + g)(x) = 3x² + x + 5

(f - g)(x) = 3x² - x - 3

Step-by-step explanation:

(f + g)(x) → f(x) + g(x) → <u>3x² + 1</u> + <u>x + 4</u>

Combine like terms and you get: 3x² + x + 5

(f - g)(x) → f(x) - g(x) → <u>3x² + 1</u> - (<u>x + 4</u>)

Remember to distribute the neg. everything in the parentheses. Combine like terms and you get: 3x² - x - 3

Could you please answer Number 2? This is for geometry
katrin [286]
Answer: 108 degrees

============================================================

Explanation:

Angle ABC is given to be 90 degrees. By the converse of Thales Theorem, we know that AC is a diameter of the circle. 
If we draw a line from A to C, it will pass through the center of the circle.

Therefore, arc AC is 180 degrees as this is half the distance around the circle.

minor arc AD = 72
minor arc CD = x
(minor arc AD) + (minor arc CD) = arc AC
72+x = 180
72+x-72 = 180-72
x = 108

minor arc CD is 108 degrees

The graph of f(x) = -x2 - 2x + 8 is shown. Which of the following describes all solutions for f(x)?
morpeh [17]

Answer:

(x, x2 -2x+8) where −5 ≤ x ≤ 3

Step-by-step explanation:

The given function is  f(x)=x2- 2x+ 8

We want to select the option that describes all the solutions to the parabola.

The domain of the parabola is −5 ≤ x ≤ 3.

This means that  any x=a on −5 ≤ x ≤ 3 that satisfies (a,f(a)), is a solution.

This can be rewritten as (a,-a2- 2a+ 8)

Therefore for x belonging to −5 ≤ x ≤ 3, all solutions are given by:

(x, x2 -2x+8) where −5 ≤ x ≤ 3.

grandymaker [24]

Answer: 2

Step-by-step explanation:

Given

The polynomial is x^4+x^3-2x^2+x+1 is divided by x-1

According to the remainder theroem

\Rightarrow x-1=0\\\Rightarrow x=1

Put x=1 in the polynomial to get the remainder

\Rightarrow 1+1-2+1+1\\\Rightarrow 2

So, we get the remainder 2.
