If a function has roots -1 and -5, it must be in the form

f(x)=a(x+1)(x+5)

We can fix the coefficient a by imposing the passing through (0,-30):

f(0)=-30=a(1)(5)\iff a=-6

So, the function is

f(x)=-6(x+1)(x+5)

Find the slope of the line containing the pair of points f(1) = -6 and f(-7) = -6.
DENIUS [597]

We have that    the slope of the line containing the pair of points f(1) = -6 and f(-7) = -6. is

m=\infty

From the question we are told

Find the slope of the line containing the pair of points f(1) = -6 and f(-7) = -6.

Where Standard form of Equation is

y=mx+c

Generally the equation for the Slope  is mathematically given as

m=\frac{y_2-y_1}{x_2-x_1}

Therefore

m=\frac{-7-1}{-6-(-6)}\\\\ m= \infty

Therefore

The slope of this line is

m=\infty

a(t) = (t - k)(t - 3)(t - 6)(t + 3) is a polynomial function of t, where k is a constant. Given that a(2) = 0, what is the absol
koban [17]
If a(2) = 0, then k=2. The product of the zeros is
(2)*(3)*(6)*(-3) = -108

The absolute value of the product of zeros of a(t) is 108.
