inverse of z^2-0.25z-0.375

inverse

z^{2} - 0.25 z - 0.375

\frac{1 + 64 z + 25}{8}, \frac{1 - 64 z + 25}{8}

Solution steps

y = z^{2} - 0.25 z - 0.375

Replace

z

with

y

z = y^{2} - 0.25 y - 0.375

Solve for

y, z = y^{2} - 0.25 y - 0.375

\frac{1 + 64 z + 25}{8}, \frac{1 - 64 z + 25}{8}

f (x) = \frac{2}{7} x + 6

f (x) = - x - 8

f (x) = 1.5 - (\frac{1}{( 0.15 x + 1 )})

y = 2 9^{x}

f (x) = 49 - x^{2}, x \geq 0
