What is the least common multiple of 90 and 54

270

Step-by-step explanation:

Find the prime factorization of 54

54 = 2 × 3 × 3 × 3

Find the prime factorization of 90

90 = 2 × 3 × 3 × 5

Multiply each factor the greater number of times it occurs in steps i) or ii) above to find the LCM:

LCM = 2 × 3 × 3 × 3 × 5

LCM = 270

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.

b. f(x) = –√x + 3this is the correct answer
