Find the equation of the parabola with vertex at the origin, focus at (3m, 0) and directrix with equation x=–3m.

Maurinko [17]

Answer:

The equation of the parabola is:

$x = 12\cdot m \cdot y^{2}$

Step-by-step explanation:

The equation of the parabola is:

$x = 4\cdot p \cdot y^{2}$

Where $p$ is equal to the distance between focus and vertex. Then,

$p = 3\cdot m$

Lastly, the equation of the parabola is:

$x = 12\cdot m \cdot y^{2}$

Find f(g(x)) and g(f(x)) of f(x)=x^2-8, g(x)=2x-5

Zina [86]

$f(x)=x^2-8\\\\g(x)=2x-5\\\\f(g(x))\to\text{instead of x write the equation of the function g(x)}\\\\f(g(x))=(2x-5)^2-8=(2x)^2-2(2x)(5)+5^2-8\\\\=4x^2-20x+25-8=4x^2-20x+17\\\\\text{used}\ (a-b)^2=a^2-2ab+b^2$

$g(f(x))\to\text{instead of x write the equation of the function f(x)}\\\\g(f(x))=2(x^2-8)-5=(2)(x^2)+(2)(-8)-5=2x^2-16-5=2x^2-21$
