Answer:
Yes, the given relation is a function.
Step-by-step explanation:
Given the quadratic function, y = (x + 1)², and the domain of {-2, -1, 0, 1, 2, 3}:
By definition, a function is a <em>relation</em> in which no two ordered pairs have the same first component (x-values) and different second components (y-values). Observing the given domain, there are no repeating <em>input</em> values.
Therefore, the correct answer is that the relation is a function.
Ok so for #18 8(x+5)-4(x+4)
you take 8X1x and 8x5
If the school has 3000 students, there are
.. (3000 -30)/27 = 110
homerooms with 27 students.
Then there were 3*110 +4 = 334 participants in the survey.
Answer:
2/19
Step-by-step explanation:
x+2 (9x) = 2
x+18x=2
19x=2
19x/19=2/19
2/19
