$x$ -intercept: $(-1.47,0)$
$y$ -intercept: $(0,-1)$

The equation can be rewritten as

$y=-x^3-x^2-1$

To find the $x$ -intercept, plug in $0$ for $y$ , and solve the equation $-x^3-x^2-1=0$ . This could be done by graphing or by a calculator.

To find the $y$ -intercept, plug in $0$ for $x$ , and then you should get $y=-1$ .

So the two intercepts are:

$x$ -intercept: $(-1.47,0)$
$y$ -intercept: $(0,-1)$

What are the intercepts of -y=x^2+x^3+1-y=x^2+x^3+1?
