Identify the x-intercepts of the function below f(x)=x^2+12x+24

ANSWER:  

x-intercepts of  

SOLUTION:

Given, -- eqn 1

x-intercepts of the function are the points where function touches the x-axis, which means they are zeroes of the function.

Now, let us find the zeroes using quadratic formula for f(x) = 0.

Here, for (1) a = 1, b= 12 and c = 24

Hence the x-intercepts of  

5+2x=a

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
