Estimation is never an effective way to get the answer. But it's always an effective way to determine whether the answer you calculated is reasonable, or from orbit by way of left field.
Answer:
A, B, D are equations representing a linear function
Step-by-step explanation:
All linear functions have an equation like the following: y=mx+b, where m is the slope and b is an offset.
A. y=x-4, m=1 and b=-4
B. y=x+4, m=1 and b=4
D. y=x+7, m=1 and b=7
The third eq dont behave like a linear function since there is quadratic term on one side of the equation, this is not a linear function
Answer:
Graphs 1, 2, 3
Step-by-step explanation:
Graph 1 represents a <u>linear function</u> with a domain containing all real numbers, as any input substituted into the equation or function will produce a corresponding output. The arrows on the opposite ends of the line represents the infinite input values that have its corresponding output values.
Graph 2 represents a <u>quadratic function</u> with a domain containing all real numbers, as it does not have any constraints in terms of input values. As it opens up, the graph of the parabola infinitely widens (horizontally).
Graph 3 represents an <u>absolute value function</u> with a domain containing all real numbers. Similar to the explanation for graph 2 on quadratic functions, the downward-facing graph of the given absolute value function widens infinitely horizontally, as it does not have any constraints on input values.
A prime number<span> has only two factors: 1 and itself. A</span>composite number<span> has more than two factors. The</span>number<span> 1 is neither </span>prime<span> nor </span>composite<span>. The </span>prime numbers<span> between 2 and 31 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29 and 31 since each of these </span>numbers<span> has only two factors, itself and 1.</span>
