Evaluate the exponential equation for three positive values....?
Evaluate the exponential equation for three positive values of x, three negative values of x, and at x=0. Show your work

y=(1/4)^x+3

  • Algebra -

    I will give you 1 positive x example and 1 negative x example, you can try some others

    let x = +2
    y = (1/4)^2 + 3
    = (1/16) = 3
    = 1/16 + 48/16 = 49/16

    let x = -3
    y = (1/4)^-3 + 3
    = (4)^(+3) + 3
    = 64 + 3 = 67

    of course if x = 0
    y = (1/4)^0 + 3
    = 1+3 = 4
