Step-by-step explanation:
Square root means that the number that if you divide it. The number that if you divide it. The number you get multiply it self, will give you the answer. 8 doesn't have a square root, because 2×2= 4,4×4= 16.so 8 doesn't have a square root. But 9 has. 1×1= 1,2×2= 4,3×3= 9.Square root of 9 is 3
The equation of the given sine graph is gotten as; y = 4 sin [(0.4(x + 2.5)] - 1
<h3>How to find the equation of a sine graph?</h3>
We know that the general formula for equation of a sine graph is;
y = A sin [(B(x - D)] + C
where;
A is Amplitude
Period = 2π/B.
Phase Shift = -C/B.
Vertical Shift = D.
From the graph;
A = 4
B = 2π/5π = 2/5
C = -1
D = -5/2
Thus;
y = 4 sin [(0.4(x + 2.5)] - 1
