Can u answers the rounded questions

Answer 1:

Here given that, x is real that is the domain

Range of the given expression is :

Write it interval form.

      Option (2)

Answer 3:

Here domain is all real x.

Range is :

{y ∈ R : y ≤ -5 or y ≥ 3}

In interval form:

(-∞, -5] ∪ [3, ∞)

So, y can't lies between -5 to 3                Option (2)

Answer 5 :

Here domain is :

x is real

And range is :

{y ∈ R : ≤ y ≤ 7}

We see that maximum y value is 7.

So, maximum value is 7.                      Option (4)

Answer 6:

Solve for x .

Square both the side

9x² + 6x + 1 =  4 + x² - 4x

8x² + 10x - 3 < 0

(2x + 3)(4x - 1) < 0

2x + 3 = 0                           &                    4x - 1 = 0

x =      &                    x =

So,

x ∈                     Option (1)

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

you,
