The value of r(x) at f(- 6) = 8.
We have the function r(x) =
We have to find the value of r(x) at x = - 6.
<h3>If f(x) = 5x + 3, then find the value of f(-2).</h3>
Substitute x = - 2 in the value of f(x) -
f(-2) = 5 (-2) + 3 = - 10 + 3 = - 7.
According to question, we have -
f(x) =
Substitute r = -6 in f(x), we have -
f(-6) =
f(-6) = - 2 x - 2 + 4
f(-6) = 4 + 4 = 8
Hence, the value of f(x) at f(- 6) = 8.
