You can put this solution on YOUR website!
equation is y = sqrt(x+4)
\n" ); document.write( "y intercept is the value of y when x is equal to 0.
\n" ); document.write( "when x is equal to 0, the equation becomes y = sqrt(4) which is equal to 2.
\n" ); document.write( "you got that part right.
\n" ); document.write( "x intercept is the value of x when y is equal to 0.
\n" ); document.write( "your equation becomes:
\n" ); document.write( "0 = sqrt(x+4)
\n" ); document.write( "square both sides of this equation to get:
\n" ); document.write( "0 = x+4
\n" ); document.write( "subtract 4 from both sides of this equation to get:
\n" ); document.write( "-4 = x
\n" ); document.write( "this is the same as:
\n" ); document.write( "x = -4
\n" ); document.write( "graph of your equation looks like this:\"
