Which graph represents y=3 sqrt x+2
ziro4ka [17]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

y=3\sqrt{x+2}

Remember that the radicand must be greater than or equal to zero

so

x+2\geq 0

solve for x

subtract 2 both sides

x\geq -2

The domain is the interval [-2,∞)

All real number greater than or equal to -2

For x=-2

y=3\sqrt{-2+2}=0

so

The range is the interval [0,∞)

All real number greater than or equal to 0

Find the y-intercept

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

For x=0

y=3\sqrt{0+2}

y=3\sqrt{2}

y=4.243

The y-intercept is the point (0,4.243)

therefore

The graph in the attached figure
