Answer:
There is no fixed domain, meaning it is ongoing
The range is from -1 ≤ x ≤ 3
It is a function
Step-by-step explanation:
Domain refers to the x values. If there was a domain then there would be a dot or a point signalling that there is a fixed domain, however, there are arrows meaning that it will keep going.
The range refers to the y-values. The lowest y-value is -1 and the highest is 3.
It is a function because, when you do the vertical line test, each x-value has its own y-value.
Answer:
Step-by-step explanation:
-4 is really -1 * 4
-4² = -1 * 4²
-4² = -1 * 16
-4² = -16
Use parenthesis to square
(-1 * 4)² = (-4)²
(-4)² = 16
Answer:
Step-by-step explanation:
12a)To rationalize the denominator, multiply the denominator and numerator by √5.
b) (a+b)² = a² + 2ab + b²
(1 +√3)² = 1² + 2*1*√3 + (√3)²
= 1 + 2√3 + 3
= 4 + 2√3
a = 4 ; b =2
13) (a + b)(a - b) = a² - b²
