The zoomster function, z(q)=4q+1/2, is used in space flight engineering. If, for some number "u", z(u+1/2)=1/2, then what is the value of "u"?
$$z(q)=4q+\frac12$$If we're given that \(z(u+\frac12)=\frac12\), we can rewrite the left-hand side by substituting in \(q=u+\frac12\) into \(z(q)=4q+\frac12\):$$4\left(u+\frac12\right)+\frac12=\frac12$$ Do you know what to do now?
solve for u. i got -1/2
Indeed, \(u=-\frac12\).
