To determine if the graph of the equation \( y = -8x^3 + x \) is symmetric with respect to the origin, we need to check if the equation remains unchanged when both \( x \) and \( y \) are replaced by their negatives.<br /><br />An equation is symmetric with respect to the origin if:<br />\[ f(-x, -y) = -f(x, y) \]<br /><br />Let's apply this to the given equation \( y = -8x^3 + x \).<br /><br />First, replace \( x \) with \(-x\) and \( y \) with \(-y\):<br />\[ -y = -8(-x)^3 + (-x) \]<br /><br />Simplify the right-hand side:<br />\[ -y = -8(-x^3) - x \]<br />\[ -y = 8x^3 - x \]<br /><br />Now, multiply both sides by \(-1\) to see if it matches the original equation:<br />\[ y = -8x^3 + x \]<br /><br />Since the equation \( y = -8x^3 + x \) remains unchanged after the transformation, it confirms that the graph of the equation is symmetric with respect to the origin.<br /><br />Therefore, the correct answer is:<br />B. The graph of the equation is symmetric with respect to the origin.
