Function: y = 4|x| - 1.
Domain: R (all real numbers).
Range: As we know, the absolute value of x is always a non-negative number:
|x| >= 0
4|x| >= 4 * 0
4|x| >= 0
4|x| - 1 >= -1
y >= -1 <----- this is the range
I hope this helps. =)
Answer:
7
Step-by-step explanation:
You would add.
So the equation would be 1 3/4+1/4 which equals 2.
I hope this helped!:)
Answer: 108deg
From picture:
10z=pi and m<SPT =6z So we know 20z=2pi or 360deg
Let’s solve:
20z=2pi
z=pi/10
m<SPT=6z=6pi/10=3pi/5 now lets take the angle from radians to degrees by unit conversion:
3pi/5*(180deg/pi)=108deg
The first claim,
"If 2<em>n</em> + 4 is even, then <em>n</em> is even"
is false; as a counterexample, consider <em>n</em> = 1, which is odd, yet 2•1 + 4 = 6 is even.
The second claim,
"If <em>n</em> is even, then (<em>n</em> + 3)² is odd"
is true. This is because
(<em>n</em> + 3)² = <em>n</em> ² + 6<em>n</em> + 9
<em>n</em> ² + 6<em>n</em> is even because <em>n</em> is even. 9 is odd. The sum of an even and odd integer is odd.
