inverse of f(x)=1.4(x-7.1)^2+2.45

inverse

f (x) = 1.4 (x - 7.1)^{2} + 2.45

0.18898 \dots 20 x - 49 + 7.1, - 0.18898 \dots 20 x - 49 + 7.1

Solution steps

y = 1.4 (x - 7.1)^{2} + 2.45

Replace

x

with

y

x = 1.4 (y - 7.1)^{2} + 2.45

Solve for

y, x = 1.4 (y - 7.1)^{2} + 2.45

0.18898 \dots 20 x - 49 + 7.1, - 0.18898 \dots 20 x - 49 + 7.1
