Answer:

f+g is right answer.

Step-by-step explanation:

given

$h(x)=(3x-4), \\f(x)=(-7x+2),\\ and g(x)=(9x+1)$ ,

2x+3 is given and we have to find the combinations of h,f and g.

By trial and error we check h+f

= -4x-2

h-f = 10x-6

So these two are not correct

Try with h+g = 12x-3 and h-g = -6x-5

Hence these are also not right

Try with f+g

(f+g)(x) = f(x)+g(x) = -7x+2+9x+1 =2x+3

Hence f+g is right.

F(x) + g(x) = (-7x+2)+(9x+1)
= 2x+3

Answer:

Y = $\frac{1}{1}x$ + 2.5

Step-by-step explanation:

This is the only valid answer for the slope.

Slope = $\frac{y2 - y1}{x2 - x1}$

Which of the following equations best describes a square root function that is reflected across the x-axis and has a vertex of (

Minchanka [31]

Answer:

Step-by-step explanation:

Rather than picking, let's try to construct one from the description.

reflected over the x axis means - $\sqrt{x}$

the vertex is usually at (0,0), now how do we move a graph? or in other words translating it.

To move left and right you use $\sqrt{x-h}$ where if you subtract h you move right and if you add h you move left. we go from (0,0) to (-4,2). so 0 to -4 is 4 left, so that means we add 4.

To move up and down we use $\sqrt{x}+v$ Here if v is positive you move up and if v is negative you move down. going from (0,0) to (-4,2) it moves up 2
