sweetsh:
Yes

astarmathsandphysics:
Itt is a staright line graph from (3,-7) to(-2,8) so the domain is -2 to 3 and the range is -7 to 8

you read the domain off the x axis and the range off the y axis

moraesikae:
when finding the range with given domain in  quadratic functions,, do you just substitude the values of the given domain into the function??

vanibharutham:
be careful with quadratics,
the range only go down to the minimum or up to maximum point

with straight line graphs you can subsitite values
however, with quadratics or cubes or absolute values, you need to basically find that turning point within your given domain

ohh thx.. so for quadratics,, you find the minimum point,, and then the maximum point of the curve by substituting to get the largest value of the domain??
