4x3-6x2+8x-5 can be written as Ax2+Bx+c+ D 2x+1 A B C D 2x+1 If logx y=2 : x=2y x=y2 y=2x x2=y x3-3x2+6x-2 has remainder 2 when divided by: x+1 x x-1 x+2 The graph of y= ex +1 crosses the y-axis at y= The graph of y= 4e-2x crosses the y-axis at y= The graph of y= -ex +1 crosses the y-axis at y= The horizontal asymptote is at y = The graph of y= 3ex +2 crosses the y-axis
at y= The graph of y= 50ex -5 crosses the y-axis
at y= The horizontal asymptote is at y = C3 Algebraic fractions and Exponential/Log functions The graph of y= 20e-x +10 crosses the y-axis
at y= The horizontal asymptote is at y = Find A to the nearest pound:
Find the investment value after 10 years: The value of an investment varies according to the formulae
V=Ae(t/12) with the investment worth £8000 after 3 years (answers to nearest pound) The graph of y= ln(x) crosses the x-axis
at x= The vertical asymptote is at x = The graph of y= ln(-x) crosses the x-axis
at x= The vertical asymptote is at x = The graph of y= ln(x-2) crosses the x-axis
at x= The vertical asymptote is at x = Solve the equation ln(3x+2) = 1, giving your answer to 2dp Solve the equation ex +e-x =2, (giving your answer to the nearest whole number). Solve the equation ln 2 +ln x = 4, (giving your answer to the nearest whole number). |
