Answer:
A perfect square is a number, from a given number system, that can be expressed as the square of a number from the same number system.
Answer:
a) (x+2)^2-2
Step-by-step explanation:
write in form of x^2+2ax+a^2
2a=4
a=2
so
x^2+4x+2^2
we will now convert into the form:
x^2+2ax+a^2=(x+a)^2
substitute the values:
x^2+4x+2^2=(x+2)^2
(x+2)^2-2+2^2
(x+2)^2-2
Answer:
B, E and F
Step-by-step explanation:
This graph is a log which has an asymptote. This means the function does not cross it and does not have in its domain certain numbers. The asymptote is at -2. This means the domain is greater than -2.
The range is the y-values. With no restrictions here, the function includes all numbers.
This means B, E, and F are true.
