Alex is 100% correct thank you so much :)
To find the zeroes of a function, we need to determine the values of x for which the function equals zero. In other words, we need to solve the equation y = x(x+5)(x+4) = 0.
To graph the function, we need to consider its x-intercepts, which are the points where the function crosses the x-axis. These x-intercepts correspond to the zeroes of the function.
To find the zeroes of the function, we set y equal to zero and solve for x:
x(x+5)(x+4) = 0
Since we have a product of three factors equal to zero, we apply the zero-product property, which states that if a product of factors equals zero, then at least one of the factors must be zero.
Setting each factor equal to zero separately, we get:
x = 0, x + 5 = 0, x + 4 = 0
Solving each of these equations, we find:
x = 0, x = -5, x = -4
Therefore, the zeroes of the function y = x(x+5)(x+4) are x = 0, x = -5, and x = -4.
To graph the function, we can plot these x-intercepts on the coordinate plane.
