Hi there! the best way of solving this is picturing out what the graph might look like. Let's assume you had the graph of a parabola y=x^2. You know that for every x you substitute, there'd always be a value for y. Thus, the domain is ALL REAL NUMBERS or from -INFINITY to + INFINITY. The range on the other hand is different. We know that any number raised to the second power will always yield a positive integer or 0. Thus, y=x^2 won't have any negative y-values as the graph opens upward. Therefore, the range is: ALL REAL NUMBERS GREATER THAN OR EQUAL TO 0. or simply: 0 to +INFINITY.
<span>On the other hand, a cubic function y=x^3 is quite different from the parabola. For any x that we plug in to the function, we'd always get a value for y, thus there are no restrictions. And the domain is ALL REAL NUMBERS or from -INFINITY to + INFINITY. For the y-values, the case would be quite similar but different to that of the y=x^2. Since a negative number raised to the third power gives us negative values, then the graph would cover positive and negative values for y. Thus, the range is ALL REAL NUMBERS or from -INFINITY to + INFINITY. Good luck!!!:D</span>
Hello! 3% interest is earned annually and $200 is added per year. 3% is 0.03 in decimal form. Let's add 1 to that number. 1 + 0.03 is 1.03. Let's multiply that by 200. 200 * 1.03 is 206. That's the amount after 1 year. Add 200 to that amount. 206 + 200 is 406. Multiply that amount by 1.03. 406 * 1.03 is 418.18. That is the amount after the second year. Now, add 200 to that amount. 418.18 + 200 is 618.18. Multiply that amount by 1.03. 418.18 * 1.03 is 636.7254 or 637 when rounded to the nearest whole number. Keep in mind that we add 200 each year and then multiply the amount by 103% (1.03) after that. There. Brandy will have about $637 after 3 years. The answer is C: $637.
X / 22 = 4 / 3 ;
x = ( 22 * 3 ) / 4 ;
x = 66 / 4 ;
x = 16,5 ;
P = 2*22 + 2*16,5 ;
P = 44 + 33 ;
P = 77 .
Answer:
you can give x a value, just make sure that the answer of the equation |x+3| is less than or equal to 4
