x(squared)+8x+17 if x < or = -4 Let f(x)= 2 if x= -4 -x(squared)-8x-15 if x > -4 Show that f(x) has a removable discontinuity at x=–4 and determine what value for f(–4) would make f(x) continuous at x=–4. Must redefine f(–4)=____

Find the EXACT VALUE of csc(-11pi/12) If that angle is in radians, it is easy. A full circle has 2PI radians...or 360 deg so 22PI/24 is the same as 22*15 deg, or -30 deg. The 30 deg triangle is well known. The sin is 1/2, so the csc is 2 Figure out the sign of the csc from ...
