Answer:
the vertex of the parabola is:(-2,0)
the focus of the parabola is:(-2,)
the directrix of the parabola is:y=
Step-by-step explanation:
we know that for any general equation of the parabola of the type the vertex of the parabola is given by (h,k)
where and
therefore by the given data we have h=-2 and k=0
hence vertex=(-2,0)
the general equation of the parabola of the type ; the parabola symmetric around the y-axis has the focus from the centre i.e. the vertex (h,k) at a distance a as (h,k+a) and the directrix is given by y=k-a
so focus is
now the directrix of the parabola is .
The equation has x Intercept at (14, 0) and Y intercept (0,6) and domain is (-2, ∞). Thus Option A,B and C are correct.
Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in set of y. x is independent variable while Y is dependent variable.
Given function,
=
Domain of the above function is grater than -2 because at -2 system goes to infinity. Domain can be given as(-2, ∞).
Given function has x intercept at (14, 0) and y intercept at (0, 6).
Thus, the given function of log has following characteristic i.e.
x Intercept at (14, 0) and Y intercept (0,6) and domain is (-2, ∞).
