Answer:
y = -5x-4
Step-by-step explanation:
start with slope-intercept form:
-9-11/1+3 = -20/4 = -5
your slope is -5
next, do point-slope form:
y+9 = -5(x-1)
y+9 = -5x+5
-9 -9
y = -5x-4
The word in the problem that indicates is a negative number is “descend”
<u>Answer-</u>
2 is the upper limit for the zeros.
<u>Solution-</u>
The given function f(x) is,

For calculating the zeros,










From all the 4 roots, it can be obtained that 2 is the greatest zero.
