A video game sets the points needed to reach the next level based on the function g(x) = 12(2)x − 1, where x is the current leve

Elden [556K]

In the function g(x) the exponent is (x - 1), so g(x) = 12 * 2 ^ (x -1)

h(x) = 3x

So, you have to find the product f(x) * h(x) for x = 6

f(6) = 12 * 2 (6 -1) = 12 * 2(5) = 12 * 32 = 384

h(6) = 3(6) = 18

f(6) * h(6) = 384 * 18 = 6912

Answer: 6912

Given the function f(x) = -2c + cx - x^2? and f^-1(5) = -1, find c.

ale4655 [162]

Answer:

c = - 2

Step-by-step explanation:

Given inverse function

$f^{-1}$ (5) = - 1 , then

f(- 1) = 5 , that is

- 2c + c(- 1) - (- 1)² = 5

- 2c - c - 1 = 5

- 3c - 1 = 5 ( add 1 to both sides )

- 3c = 6 ( divide both sides by - 3 )

c = - 2

What is 3/4(x2+4x+6)=13x-2

maxonik [38]

Answer:

$x_1=12.65\\\\x_2=0.685$

Step-by-step explanation:

$\frac{3}{4}(x^2+4x+6)=(13x-2)\\\\Multiply\ both\ sides\ by\ 4.\\\\3(x^2+4x+6)=4(13x-2)\\\\3x^2+12x+18=52x-8\\\\3x^2+12x+18-(52x-8)=0\\\\3x^2+12x-52x+18+8=0\\\\3x^2-40x+26=0$

Roots of Polynomial:

$Roots\ are\ polynomial\ ax^2+bx+c=0\\\\x=\frac{-b\pm \sqrt{(b^2-4ac)}}{2a}$

$Here\ a=3,\ b-40,\ c=26\\\\x=\frac{-(-40)\pm \sqrt{(-40)^2-4\times 3\times 26}}{2\times 3}\\\\x=\frac{40\pm\sqrt{1288}}{6}\\\\x_1=\frac{40+\sqrt{1288}}{6}\approx 12.65\\\\x_2=\frac{40-\sqrt{1288}}{6}\approx 0.685$
