Answer:
there is a fraction calculator you can use
https://www.calculatorsoup.com/calculators/math/fractions.php
Step-by-step explanation:
Domain: the smallest possible x-value to the largest possible x-value
In the case of this graph, we see the parabola starts at x = -3, and continues on forever.
Domain: [-3, infinity)
Range: the smallest possible y-value to the largest possible y-value
In the case of this graph, the parabola will continue to expand forever.
Range: (-infinity, infinity)
Therefore, while the domain has a restriction, the range does not and is all real numbers.
Hope this helps!
Answer:
y = -2x + 9
Step-by-step explanation:
I'm going to use the points
(1,7) and (4,1)
1-7/4-1 = -2 = m
y - 7 = -2 (x - 1)
y - 7 = -2x + 2
y = -2x + 9
