Given that f(n) = n^2 - 4n + 3 & g(n) = 2n - 1 find gf(-2)

icang [17]

Answer:

The value of $gf\left(-2\right)$ will be:

$gf\left(-2\right)=29$

Step-by-step explanation:

Given the functions

$f(n) = n^2 - 4n + 3$

$g\left(n\right)\:=\:2n\:-\:1$

$f\left(-2\right)\:=\:\left(-2\right)^2\:-\:4\left(-2\right)\:+\:3$

$=\left(-2\right)^2+4\cdot \:2+3$

$=2^2+4\cdot \:2+3$

$=2^2+8+3$

$=4+11$

$=15$

$gf\left(-2\right)=g\left(15\right)$

$=2n-1=2\left(15\right)-1=30-1=29$

Therefore,

$gf\left(-2\right)=29$

Which graph represents the solution set of the system of inequalities?

lidiya [134]

$y < \dfrac{2}{3}x\\\\y=\dfrac{2}{3}x\\\\for\ x=0\to y=\dfrac{2}{3}(0)=0\to(0,\ 0)\\\\for\ x=3\to y=\dfrac{2}{3}(3)=2\to(3,\ 2)\\\\y\geq-x+2\\\\y=-x+2\\\\for\ x=0\to y=-0+2=2\to(0,\ 2)\\\\for\ x=2\to y=-2+2=0\to(2,\ 0)$

$y < \dfrac{2}{3}x$
