Answer:

f(x)=(x+4)(x-7)(x-1)

Step-by-step explanation:

zeroes are when you plug in that x value and get y=0

therefore if you set x = that number and solve for 0 you get a "function"

multiplying these together will yield the complete 3rd degree polynomial

x = 1

x-1=0

x=7

x-7=0

x=-4

x+4=0

f(x)=(x+4)(x-7)(x-1)

If needed you could expand but I'm too lazy

After which value of x does function g exceed function f
nalin [4]
We have that

for x=1
f(x)=1.5  and g(x)=-1
so
g(x) < f(x)

for x=2
f(x)=5  and g(x)=5
so
g(x)= f(x)

for x=3
f(x)=9.5  and g(x)=23
so
g(x) > f(x)

therefore

the answer is
<span>After x=2 function g exceeds function f</span>

A right prism with rhombus bases is shown. The side length of each rhombus is 5 units. The height of the prism is 16 units. The
Papessa [141]
Volume of the prism:
V = B · h, where B stays for the area of the base and h stays for the height of the prism. And we know that d1 = 8, d2 = 6
B = ( d1 · d2 ) / 2 = ( 8 · 6 ) / 2 = 48 / 2 = 24
V = 24 · 16  = 384
Answer:
The volume of the prism is 384 cubic units.
