Select the correct answer.
solve the following equation for
80x2 + 92x – 84 = 0

x = 0.6 and x = -1.75

Step-by-step explanation:

80x2+92x−84=0

Use quadratic formula

x = (−b ±√(b2−4ac))/√2a

x = (-92 ± √(35344)) / 160

x = 95/160 and x = -280 / 160

x = 0.6 and x = -1.75

step-by-step explanation:

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
