Hello from MrBillDoesMath!
Answer: A, C, D
Discussion:
The solution of the quadratic equation ax^2 + bx + c = 0 is
x = ( -b +\- (b^2 - 4ac) ^ (1/2) ) /2a
The expression b^2 - 4ac is called the discriminant, occurs in the numerator of the solution, and also occurs inside a square root (called a radicand).
The question, while intelligible, should be stated more clearly.
Regards, MrB
The answer is E, the fifth answer choice,
slope = -1; y-intercept = 5
Hope this helps :)

Answer:
a:non linear
y-intercept=1
smallest postive x-intercept: π
y= 1 and x=0
Step-by-step explanation:
1.a:non linear
("Linear means something related to a line. All the linear equations are used to construct a line. A non-linear equation is such which does not form a straight line. It looks like a curve in a graph and has a variable slope value.")
2.The y-intercept is 1
The point where x is zero(0) is the y-intercept
(0,1)
3. smallest positive x intercept is
so x-intercept is point where y is 0
look at the paterns (pi,0) and (-pi,0) etc..
The smallest positive x-intercept is
(π,0)
4. The greatest value of y is y= 1 and x=0

Its B
