Mathematics
1 answer:
enyata [817]3 years ago
3 0

Answer:

D, the horizontal line is a function

Step-by-step explanation:

To pass the vertical line test, a vertical line cannot go through the function more than once

A is a vertical line so it will fail the vertical line test

B will fail the vertical line test at many points.  One example is at

x =0 where you can see it will intersect at two points

C will fail the vertical line test at many points.  One example is at

x =0 where you can see it will intersect at two points

D is a horizontal line.  This will pass the vertical line test

Write an inequality for the given graph.
Gekata [30.6K]

Answer:

y

Step-by-step explanation:

<em>Find the equation of the dashed line</em>

The line pass through the points

A(0,-3) -----> is the y-intercept of the line

B(6,0)

Find the slope of the line m

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

substitute the values

m=\frac{0+3}{6-0}=0.5

Remember that

The equation of the line into slope intercept form is equal to

y=mx+b

we have

m=0.5

b=-3  

substitute

y=0.5x-3

<em>Find the inequality</em>

we know that

The solution of the inequality is the shaded area below the dashed line

so

y
