Answer:
Domain: All real numbers
Range: y≤3
Step-by-step explanation:
The given function is
This is a polynomial function.
The domain is set of all values of x, that makes this function defined.
Since polynomial functions are defined everywhere, the domain is all real numbers.
To find the range we put the function in vertex form:
The maximum value is 3
The function turns downward, hence the range is:
Answer:
it is a linear expression

Answer:
x intercept at (7/3 , 0)
y intercept at (0,-3)
Step-by-step explanation:
9x-7y=21
we need to find x and y intercepts
To find x intercept , plug in 0 for y
9x - 7(0) = 21
9x = 21
divide by 9 on both sides
x= 21/ 9 = 7/3
so x intercept at (7/3 , 0)
To find y intercept , plug in 0 for x
9(0) - 7(y) = 21
-7y = 21
divide by -7 on both sides
y= -3
so y intercept at (0,-3)
