each solution is negative.
there are infinite solutions.
the solutions contain rational number values.
there are no positive values as solution is less that -20.
the solution contains fractional values as well as integers.
some rational numbers in the solution are -21, -21 1/2 , -23.4 which are rational.
a quadratic function is a function in which the highest degree term is 2.
when the degree is two and the equation is a quadratic then the graph looks like a parabola always .
in the given options only option c is parabola so correct option is c.
option a is not parabola .(it is for cubic)
option b is a straight line means linear function .
option d cuts the x axis more than 2 times so it cannot be a quadratic .
so correct option is c
i took the test & got 100%. also its what calculator says, so, ya know.
suppose dd', ee', and...
