No its not. the square root of 15 is about 3.873. Thus, the square root of 15 is not an integer, and therefore 15 is not a square number.
Answer:
h(1) = 1, h(2) = 3, h(3) = 4
Step-by-step explanation:
Given function h(x)
<u>Need to find :</u>
<u>h(1) falls under the second condition as -2 ≤1<2:</u>
- h(1) = - (x-1)² + 1 = -( 1 - 1)² + 1 = 1
<u>h(2) and h(4) fall under the third condition as x=2,4 ≥ 2:</u>
- h(2) = 1/2x + 2 = 1/2*2 + 2 = 1 + 2 = 3
- h(4) = 1/2x + 2 = 1/2 * 4 + 2 = 2 + 2 = 4
