Case II: a = 0 The graph of the right-hand side of x2 = 0 is a horizontal line that coincides with the x-axis. The graph of y = x2 intersects the graph of y = 0 at one point, at the vertex of the parabola. Thus, the only solution of x2 = 0 is x = 0, as seen in Figure 2 (b).
WebAlthough even roots of negative numbers cannot be solved with just real numbers, odd roots are possible. For example: (-3) (-3) (-3)=cbrt (-27) Even though you are multiplying a negative number, it is possible to obtain a negative answer because you are multiplying it with itself an odd number of times. Let's walk through it a little more slowly: WebApr 11, 2024 · The engineering of carbon nanotubes in the last decades resulted in a variety of applications in electronics, electrochemistry, and biomedicine. A number of reports also evidenced their valuable application in agriculture as plant growth regulators and nanocarriers. In this work, we explored the effect of seed priming with single-walled …
WebWhen the index of the radical is even, the radicand must be greater than or equal to zero. When the index of the radical is odd, the radicand can be any real number. Find the domain of the function, Write the domain in interval notation. Since the function, has a radical with an index of 2, which is even, we know the radicand must be greater ...
