Given f(x)=3x(to the scnd power)−5x−2. What is the value of f(−2/3)? 1 8/3 3 10/3

Given that y varies directly to the square root of (x + 1), and that y = 1 when x = 8,(a)express y in terms of .x,(b)find the value of y when x = 3,(c)find the value of x when y = 5.

If t8 = 4 and t12 = −2, find the first three terms of the arithmetic sequence.

If f(x)=3 over x+2 - square root x-3 then f(7)=
