(a) Given that A = {1, 2, 3, 4} and B = {4, 5, 8, 10, 11, 12, 14, 15). Is the function f : A B defined by f(x) = 3x + 2 one to one and into? Give reasons.​

The following division is being performed using multiplication by the reciprocal find the missing numbers is 5/12 divided by x/3 equals 5/12 times x/10 equals 1/x

X^2/100+y^2/25=1 the y-intercepts are at: a) (-10,0) and (10,0) b) (0,10) and (0,5) c) (0,-5) and (0,5)
