Evaluate the function when x=-3,0 and 2. F(x)=15x+4

f(x) = 15x + 4 x = -3: f(x) = 15x + 4           f(-3) = 15(-3) + 4           f(-3) = -45 + 4           f(-3) = -41      (x, f(x)) = (-3, -41) x = 0: f(x) = 15x + 4           f(0) = 15(0) + 4           f(0) = 0 + 4           f(0) = 4     (x, f(x)) = (0, 4) x = 2: f(x) = 15x + 4           f(2) = 15(2) + 4           f(2) = 30 + 4           f(2) = 34     (x, f(x)) = (2, 34)
