A function f(x) = x^2 - 4 has a domain as the set of integers
1 answer:
Answer:
8
Step-by-step explanation:
f(x) = (x+2)(x-2)
Substituting x=1 into f(x):
f(1) = 3*-1
= -3
Since -2 & 2 touch the x-axis, 1 has a negative y value, 2 has a y value of 0, and all values from 2, are positive.
Hence,
3, 4, 5, 6, 7, 8, 9, 10 are all positive. Therefore, the answer is 8
This can be confirmed with a graph, as attached below.

Answer:
choice C. Perfect square trinomial is correct.
Step-by-step explanation:
We need to find the pattern which is represented by the polynomial .
To find that pattern, we need to factor
which is a perfect square.
Hence choice C. Perfect square trinomial is correct.
Hi!
This question is about math.
<u><em>Least Common Factor 4 or 8: 8</em></u>
<u><em>Factors of 4 : 1, 2, 4 (prime factorization) (2*2)</em></u>
<u><em>Factors of 8: 1, 2, 4, 8 (prime factorization) (2*2*2)</em></u>
<u><em>Least Common Factor of a,b is the smallest positive number that divisible by both a and b.</em></u>
<em>Multiply each factor the greatest number of times it occurs in either 4 or 8.</em>
<em>Then multiply by the numbers.</em>
<em>Multiply each numerator by the same amount needed to multiply its corresponding denominator to turn it into the Least Common Factor of 8.</em>
<em>For 1/4 multiply the denominator and numerator by the 2.</em>
<em>Since the denominator are equal, combine the fractions.</em>
<em>Add the numbers 2+5=7</em>
Hope this helps! Thank you for posting your question at here on Brainly. Have a great day.
