Answer:
Step-by-step explanation:
The original price on the item is the price before a markup of 110% of this original price:
original price + 1.10(original price) = 2.10(original price)
Ok, first group x terms
f(x)=(x²+4x)-8
factor out quadratic coefient (no need but that's the step)
f(x)=1(x²+4x)-8
take 1/2 of the linear coefient and square it
4/2=2, (2)²=4
add positive and negative of it insides the parenthasees
f(x)=1(x²+4x+4-4)-8
factor perfect square
f(x)=1((x+2)²-4)-8
distribute
f(x)=1(x+2)²-4-8
f(x)=1(x+2)²-12
and, now if we wanted to find the x intercepts where f(x)=0 then
0=1(x+2)²-12
12=(x+2)²
+/-2√3=x+2
-2+/-2√3=x
x=-2+2√3 or -2-2√3
that is where the x intercept are
and completed square form is
f(x)=(x+2)²-12
Answer:
Step-by-step explanation:
x^2 + 24x + 144 is a perfect square: (x + 12)². The square root of this is
±(x + 12).
g(x) = square root of x^3 -216 = √(x^3 - 216), or
√(x³ - 6³). x³ - 6³ is not a perfect square, altho' it can be factored.

Answer:
1st Option.
Step-by-step explanation:
f(0) = g(0) is correct because both f(0) = -2 and g(0) = -2; they both intersect at that point and therefore the y-value is the same.
The other answer choices don't work because the y-value outputs don't match each other.
