1) \( x(t)=t^{2}+3 t \) funksiya berilgan bo'lsa, ikkinchi tartibli ayirmani, ya'ni \( \Delta^{3} \) ni aniqlang. \( \Delta^{3}= \) ? 2) Bir ko'rinishdan boshqasiga o'ting \( 10 \Delta^{3} y[n]+3 \Delta y[n]+8=f[n] \); 3) Z tasvirni toping \( 10 y[n+3]+2 y[n+2]+5 y[n]=f[n] \);

Graph the polynomial function \( f(x)=(x+1)^{2}(x-6)^{2} \) using parts (a) through (e). The graph of \( f \) behaves like \( y=x^{4} \) for large values of \( |x| \). (b) Find the \( x \) - and \( y \)-intercepts of the graph of the function. The \( x \)-intercept(s) is/are \( -1,6 \). (Simplify your answer. Type an integer or a fraction. Use a comma to separate answers as needed. Type each answer only once.) The \( y \)-intercept is 36 . (Simplify your answer. Type an integer or a fraction.) (c) Determine the zeros of the function and their multiplicity. Use this information to determine whether the graph crosses or touches the \( x \)-axis at each \( x \)-intercept. The zero(s) of \( f \) is/are (Simplify your answer. Type an integer or a fraction. Use a comma to separate answers as needed. Type each answer only once.)
