\large\underline{\rm Solution }:-

Given function to us is ,

\implies f(x) = 3x^3 - 5x + 1

The domain of the expression will be all <u>real </u><u>numbers</u> except where the given expression is not defined . Therefore , the domain is ,

\underline\text{ In Interval Notation :- }

\implies \boxed{ Domain : ( -\infty , +\infty ) }

\underline\text{ In Set Builder Notation :- }

\implies \boxed{ Domain : \{ x | x \in \mathbb{R} \}}

In triangle ABC AB is equals to AB and Angle B equal to 80 find the angle A​
insens350 [35]

Answer:

∠A = 20°

Step-by-step explanation:

Given:

Line AB equal to line AC

So, we can say that;

∠B = ∠C

So

∠B = ∠C = 80°

Using angle sum rule

∠A + ∠B + ∠C = 180°

∠A + 80° + 80° = 180°

∠A = 20°

<h3>What is the triangle?</h3>

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

The similar triangles are shown in the diagram.

16 / x = x / 5

    x² = 16 × 5

      x = 4 √5

Then the value of the variable is 4√5.

Then the correct option is C.

More about the triangle link is given below.

Solve for the value of x 3x - 9 + 12 - 6x = -18
Daniel [21]

Answer:

x =7

Step-by-step explanation:

3x - 9 + 12 - 6x = -18

Combine like terms

-3x +3 = -18

Subtract 3 from each side

-3x +3 -3 = -18 -3

-3x = -21

Divide each side by-3

-3x /-3 = -21 /-3

x =7
