Answer:
Step-by-step explanation:
The graph that represents the function
f(x) = (x + 4)(x + 1)(x - 3)
crosses the x-axis three times: at x = -4, x = -1, and x = 3
because we apply the zero product rule and found the roots -4, -1, and 3
x+ 4= 0 → x = -4
x+1 = 0 → x = -1
x-3 = 0 → x = 3
There are 10 fish in the tank
<em><u>Solution:</u></em>
Given that, volume of a tank is 50 cubic feet
Density is 0.2 fish over feet cubed
<em><u>To find: Number of fish in the tank</u></em>
Number of fish in the tank is found by multiplying the volume of tank and density
<em><u>The formula is given by:</u></em>
<em><u>Substituting the given values, we get</u></em>
Thus there are 10 fish in the tank
