$2x12$

At least one of the answers above is NOT correct.

$(1$ point$)$ Suppose $f(x)=11-x^2$

$($a$)$ Find the slope of the tangent line to the graph $y=f(x)$ when $x=-1.$

Slope $=\underset{h0}{lim}(\frac{f(xh)-f(x)}{h})=\underset{h0}{lim}()=$

$($b$)$ Find an equation for the tangent of to the curve $y=f(x)$ at the point $(-1,10).$

Tangent line: $y=$

$($c$)$ On a piece of paper, sketch the curve $y=f(x)$ and the tangent line together.
