Question

Draw the graphs of each of the following polynomial and if possible ,read the zeroes from the graph a) x2 - 2x + 9​

Answer 1

Given that,

The equation is $x^2-2x+9$

The function is $y=f(x)$

We need to calculate the point of x and y

Using given function

$y=x^2-2x+9$

Put the value of x = -5

$y=(-5)^2-2\times-5+9$

$y=44$

Then the value of y = 44

Now, x = -4 then y = 33

x = 0 then y = 9

x = 4 then y = 17

x = 5 then y = 24

So , The point for graph will be

$(x,y)=(-5,44), (-4, 33), (0,9), (4,17), (5, 24)$

We draw the graph from these points.

Hence, This is required answer.
