X6 – 9x3 + 8 = 0
let u = x^3
u^2 - 9u + 8 = 0
(u-8)(u-1) = 0
u = 1,8
back substitute
1 = x^3
8 = x^3

<span>x = 1 , 2</span>

Answer:

Step-by-step explanation:

Finding the vertex or the end of the shape.

Find the y -intercept, (0,f(0)) ( 0 , f ( 0 ) ) .

Solve f(x)=0 f ( x ) = 0 to find the x coordinates of the x -intercepts if they exist.

Make sure that you've got at least one point to either side of the vertex. ...

Sketch the graph.

$f(x) = x + 7$

$h(x) = - 2x + 1$

Add them up :

$f(x) + h(x) = x + 7 - 2x + 1 \\$

Collect like terms

$f(x) + h(x) = - x + 8$
