For a=−4, state the b values giving (i) no x-axis intercepts; (ii) four distinct x-axis intercepts.
Now set a=4. State the b values giving (i) exactly one intercept; (ii) no intercepts; (iii) exactly two intercepts.
If F has four distinct x-axis intercepts, state where its local maximum and its two local minima lie relative to the x-axis.
For a<0, show that the stationary points are P = (0, b) and .
Assume a<0 and b>a²/4. For P = (0, b) and : (i) find F″ and classify each stationary point; (ii) state whether these points lie above or below the x-axis.
Assume a>0, so P=(0,b) is the only stationary point. (i) When b>0, state its type and position relative to the x-axis. (ii) For this positive a, state the condition on b placing P below the x-axis.
Prove that a<0 and 0<b<a²/4 imply exactly four distinct x-axis intercepts.
Write an expression for (g∘f)(x).
Given (g∘f)(1) = 25, find all possible k.
