Let f(x)=-4x+7 and g(x)=10x-6. Find f(g(x))

olga55 [171]

$f(x) = -4x+7 \\ g(x) = 10x-6$

To find f(g(x)), insert the equation of g(x) into the x value for f(x)

$f(g(x)) = -4(10x-6)+7 \\ f(g(x)) = -40x + 24 +7 \\ f(g(x)) = -40x + 31$

Which is the equation of the parabola?

Umnica [9.8K]

Answer: $y=-\dfrac{1}{8}(x - 2)^2 - 3$

<u>Step-by-step explanation:</u>

The vertex form of a parabola is: y = a(x - h)² + k where

(h, k) is the vertex
$a=\dfrac{1}{4p}$

NOTE: p is the distance from the vertex to the focus

The vertex (h, k) is (2, -3)

$p=-2\quad \implies\quad a = \dfrac{1}{4(-2)}=-\dfrac{1}{8}$

Insert those values into the vertex formula to get:

$y=-\dfrac{1}{8}(x - 2)^2 - 3$
