Question

fill in the blank. if the graph of an equation is symmetric with respect to the y - axis and - 4 is an x - intercept of this graph, then ______ is also an x - intercept. if the graph of an equation is symmetric with respect to the y - axis and - 4 is an x - intercept of this graph, then \\(\square\\) is also an x - intercept. (type an integer or a fraction.)

Explanation:

A graph symmetric about the y-axis means if $(a,0)$ is an x-intercept, then $(-a,0)$ is also an x-intercept. For the intercept $-4$, its positive counterpart is the matching intercept.

Answer:

$4$
