Just type it the regular way, so far I can make out the following ....
f(x) = 5x + 7 ; (-3,0)
I will interpret (-3,0) as interval notation and -3 < x < 0
f(-3) = -8, f(0) = 7
domain (-3,0), range (-8,7)
the min approaches -8
the max approaches 7
For the following linear function, find the domain, range, and intercepts. Then find the minimum and maximum values of f left parenthesis x right parenthesis on the given interval. Write the domain and range in interval notation.
f left parenthesis x right parenthesis equals 5 x plus 7; left bracket negative 3 comma 0 right bracket

words, words, words!! How about
f(x) = 5x+7 on the interval [-3,0]
Clearly the domain is [3,0]
You know this is just a straight line, so the range is all the y values between f(-3) and f(0).
Now surely you can figure the min and max values of y.
