x= 3+√5/4,3-√5/4
Step-by-step explanation:
1.In general, given ax^2+bx+c=0, there exists two solutions where:
x= -b+√b^2 - 4ac/2a, -b-√b^2-4ac/2a
2.In this case, a=4, b=-6 and c=1.
x=6+√(-6)^2-4×4/2×4, 6-√(-6)^2-4×4/2×4
3.Simplify.
x=6+2√5/8, 6-√5/8
4.Simplify solutions.
x=3+√5/4, 3-√5/4
-5c^2-3c+4 This polynomial is in standard form, now, and the leading coefficient is 5, because it is the coefficient of the first term. Degree is 2, due to -5c^2.

Answer:
Domain { 4,8,12,16,20}
Range { 1,2,3,4}
This is not a function because two of the inputs have more than one output
Step-by-step explanation:
The domain is the x values ( input)
Domain { 4,8,12,16,20}
The range is the y values (output)
Range { 1,2,3,4}
This is not a function because two of the inputs have more than one output
