Which equation, when solved, results in a different value of x than the other three?
16 - () --2-20
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
answer: the standard form of equation will be
since we have given that
the vertex form of equation is given by
we need to find the standard form :
standard form is written as :
so, our equation becomes,
hence, the standard form of equation will be
y = 1/4x+1
we have 2 points so we can find the slope
m = (y2-y1)/ (x2-x1)
the point (0,1) is the y intercept
we find the y intercept when x=0
we want to find the equation in slope intercept form
y= mx+b where m is the slope and b is the y intercept
y = 1/4x+1
