Anit [1.1K]

Answer:

False

Step-by-step explanation:

If this number is larger than 6, then its square is larger than 36.

If x > 6, then x² > 36

The number is not larger than 6.therefore Its square is not larger than 36.

x ≤ 6; therefore, x² ≤ 36

-7 is < 6; however -7² > 36 as -7² = 49

A parabola can be represented by the equation y2 = –x. What are the coordinates of the focus and the equation of the directrix?

shutvik [7]

ANSWER

Focus:

$(- \frac{1}{4} ,0)$

Directrix:

$x=\frac{1}{4}$

EXPLANATION

The given parabola has equation:

${y}^{2} = - x$

We compare this to the general equation,

${y}^{2} = - 4px$

Comparing the coefficient of x, we have:

-4p=-1

$p = \frac{1}{4}$

The focus is (-p,0)

$(- \frac{1}{4} ,0)$

The equation of the directrix is

x=p

$x = \frac{1}{4}$
