sketch the graph of the given function. In each case determine whether f is continuous, piecewise continuous, or neither on the interval 0 ≤ t ≤ 3.  1.f(t)=⎧⎪⎨⎪⎩t2,0≤t≤12+t,1<t≤26−t,2<t≤3

The following function is continuous and defined on the closed interval. It therefore satisfies the assumptions of the extreme-value theorem. With the help of technology, graph each function and locate its global extrema. f(x) = − x² + 1, −1≤x≤1 Graph the function. Choose the correct answer below. O A. B. -6 HHHH -6 -6 6- D. -6- -6

Find all values x = a where the function is discontinuous. if x 5 O a = 5 O a=0 O Nowhere O a = 0,5 Q

Let the function f be defined b √x+4 If x=-3 f(x)=30.5x²=-2 if-3
