Q. f(x)={(x1)2+1 for 1x<41 for x=46x32 for x>4 f(x)=\left\{\begin{array}{lll} -(x-1)^{2}+1 & \text { for } & 1 \leq x<4 \\ -1 & \text { for } & x=4 \\ 6 x-32 & \text { for } & x>4 \end{array}\right. \newlineFind f(4) f(4) \newlineAnswer:\newline
  1. Identify Interval for x=4x=4: Identify the correct piece of the piecewise function to use for x=4x = 4.\newlineThe function f(x)f(x) is defined differently for different intervals of xx. Since we are looking for f(4)f(4), we need to use the definition of f(x)f(x) that applies when x=4x = 4.
  2. Use Definition for x=4x=4: Use the definition of f(x)f(x) for x=4x = 4. According to the given piecewise function, f(x)=1f(x) = -1 when x=4x = 4.
  3. Calculate f(4)f(4): Calculate the value of f(4)f(4).\newlineSince f(x)=1f(x) = -1 for x=4x = 4, we have f(4)=1f(4) = -1.
