$\displaystyle f: R -> R, f (x) = ( x + 4 ) ( x^2 - 4x +13 )$
Find the Y intercept of the graph.
Explain why there is no real solution to the equation f(x)=0
Find the stationary points of y= f(x).
just plug in x = 0 and solve
this is not true, f(-4) = 0, -4 is a real numberExplain why there is no real solution to the equation f(x)=0
find f'(x) and set it equal to zero, use the product rule if you don't want to expand everythingFind the stationary points of y= f(x).
