Statement 1 is false.

While it is true that some of the y-values have more than one corresponding x-value, this does not make the relation not a function.  It would not be a function if some of the <em>x-values</em> had more than one corresponding y-values.

Statement 2 is true.

The domain of a function is all the x-values it encompasses.  This function starts at 3 and ends at 8.

Statement 3 is false.

The range of a function is all the y-values it encompasses.  This includes all the y-coordinates, but it does not express the range properly.  The range is [6, 10].

Hope this helps!!

The equation of line AB is y = 2x + 4. Write an equation of a line parallel to line AB in slope-intercept form that contains poi
bazaltina [42]

Answer:

The equation would be y = 2x - 8

Step-by-step explanation:

The equation of the line would have a slope of 2, since parallel lines have the same slope. We can use that and the point in point-slope form to find the equation.

y - y1 = m(x - x1)

y + 2 = 2(x - 3)

y + 2 = 2x - 6

y = 2x - 8

You can upgrade lighting at your factory to LED bulbs that cost $6.95 each and last an average of 5 years. It costs S3 in labor
marshall27 [118]

Answer:

11.95 dollars

Step-by-step explanation:

Cost of one LED bulb = 6.95 dollars

Cost of changing one bulb = 3 dollars

Life of each bulb = 5 years.

In 10 years, only one time after 5 years the bulbs would have been changed

Hence cost of 100 lamps = 695 and

cost of changing once = 500

Total cost = 1195 dollars for 11 years

Divide this by 10 years to get average cost per year

Cost of 100 lamps per year = 1195/100 = 11.95 dollars
