Answer:

The graph in the attached figure

Step-by-step explanation:

we have

$y=-\sqrt{x+1}$

Find the intercepts

The y-intercept is the value of y when the value of x is equal to zero

For x=0 -----> $y=-\sqrt{0+1}=-1$

The y-intercept is the point (0,-1)

The x-intercept is the value of x when the value of y is equal to zero

For y=0 -----> $0=-\sqrt{x+1}$ -----> $x=-1$

The x-intercept is the point (-1,0)

Find the domain

we know that

The radicand must be positive

$x+1\geq0$

$x\geq-1$

All real numbers greater than or equal to -1

The range is all real numbers less than or equal to -1

using a graphing tool

see the attached figure

5x - 7x + 6 = -2 (x - 3) Or... Are there no solutions or infinite solutions

MissTica

Answer:

there are no solutions

Step-by-step explanation:

5x−7x+6=−2(x−3)

Step 1: Simplify both sides of the equation.

5x−7x+6=−2(x−3)

5x+−7x+6=(−2)(x)+(−2)(−3)(Distribute)

5x+−7x+6=−2x+6

(5x+−7x)+(6)=−2x+6(Combine Like Terms)

−2x+6=−2x+6

Step 2: Add 2x to both sides.

−2x+6+2x=−2x+6+2x

6=6.

Step 3: Subtract 6 from both sides.

6−6=6−6

0=0

there for there are no solutions

The function g(x) = x^2 + 3. The function f(x)= g(x+2)

Leno4ka [110]

Answer:

The function f(x) is shifted horizontally left by 2 units.

Step-by-step explanation:

Given the function is g(x) = x² + 3.

Now, f(x) = g(x + 2) = (x + 2)² + 3

Therefore, for a certain value of y, the x-value of function g(x) will be 2 units more than that of function f(x).

Therefore, the function f(x) is shifted horizontally ( the x-axis is the horizontal axis) left by 2 units compared to the function g(x). (Answer)

The length of a rectangle is 4 less than three times the width. The area of the rectangle is given by the formula A = l × w. Whi

Masja [62]

Answer:

C) A = $3w^{2} - 4w$

Step-by-step explanation:

First, read through what the question is asking.

Now, read it again, but slowly and take in everything it is saying (Don't read into it too slowly, or else you will over-complicate the problem and get frustrated - told from experience :) )

Alright, 4 less than 3 times the width. So, lets rearrange this and give width a variable (w).

So, the length is equal to:

l = 3w - 4

and the width is equal to:

w = w

The area of a rectangle is A = l * w

Let's plug in the values.

A = (3w - 4) * w

Now, simplify:

A = $3w^{2} - 4w$

A = $3w^{2} - 4w$ is your final answer.

I hope this helps!
