Let g(x) = 2x and h(x) = x^2 + 4. Find the value.(g o h) (0)a) 4b) 8c) 0d) 16

Paul [167]

$\begin{gathered} \text{Given} \\ g(x)=2x \\ h(x)=x^2+4 \end{gathered}$

Solve for (g o h)(x)

$\begin{gathered} (g\circ f)(x)=g\big(f(x)\big) \\ (g\circ f)(x)=g(x^2+4) \\ (g\circ f)(x)=2(x^2+4) \\ (g\circ f)(x)=2x^2+8 \end{gathered}$

Next substitute x = 0

$\begin{gathered} (g\circ f)(x)=2x^2+8 \\ (g\circ f)(0)=2(0)^2+8 \\ (g\circ f)(0)=8 \end{gathered}$ $\text{Therefore, }(g\circ f)(0)=8$

Find the equation of the line through the points (9,−2) and (1,6).

devlian [24]

Answer: y=-x+7

Step-by-step explanation:

Answer:

Your given points: (9,-2)and (1,6)

x1=9

y1=-2

x2=1

y2=6

Step-by-step explanation:

To find slope take the points you got from graph and put it into the equation y2-y1/x2-x1

6-(-2)/1-9=6+2/1-9=8/-8=-1

SLOPE IS m=-1

Then take that slope u got and plug into this equation to find equation of the line

y-y1=m(x-x1)

y-(-2)=-1(x-9)

y+2=-x+9

-2. -2
