The image presents four graphs, each with corresponding function estimates to solve. Let's go through them step by step:

1. Graph 1: $g(x) = -5\sqrt{x} + 50$

   • Estimate $g(6), g(12), g(19)$ using the graph.

2. Graph 2: $g(x) = x^3 - 8x^2 + 8x$

   • Estimate $g(-2), g(1), g(8)$ from the graph.

3. Graph 3: $f(x) = |x| + 2$

   • Estimate $f(-8), f(-3), f(0)$ from the graph.

4. Graph 4: Piecewise function $P(x)$

   • Estimate $P(-6), P(2), P(9)$.

I'll guide you through solving each one. Let's start with Graph 1, where we'll estimate the values directly from the graph. Would you like detailed assistance with each part?
