Answer:

$x=-\frac{1}{5} \:or \: x=2 \:or\: x=-6$

Step-by-step explanation:

Given $f(x)=(5x+1)(4x-8)(x+6)$

The zeros of the polynomial function are the point where the function f(x) equals zero.

$f(x)=(5x+1)(4x-8)(x+6)=0$

If abc=0, then a=0 or b=0 or c=0

Therefore:

$(5x+1)(4x-8)(x+6)=0 \:means\\5x+1=0 \:or \: 4x-8=0 \:or\: x+6=0\\5x=-1 \:or \: 4x=8 \:or\: x=-6\\x=-\frac{1}{5} \:or \: x=2 \:or\: x=-6$

Choose the point-slope form of the equation of this line.

igor_vitrenko [27]

Answer:

y= -5x +7

Step-by-step explanation:

We can see points on the graph:

(2, -3) and (3, -8)

The function in general form is:

y= mx+b

Let's find the slope and y-intercept as per identified points on the graph:

m= (y1-y1)/(x2-x1)

m= (-8+3)/(3-2)= -5

b= y- mx

b= - 3 -(-5)*2= -3 +10= 7

Based on the found values of m and b, the given line is:

y= -5x +7
