Problem 30
Question
Evaluate each function at the given values of the independent variable and simplify. \(g(x)=x^{2}-10 x-3\) a. \(g(-1)\) b. \(g(x+2)\) c. \(g(-x)\)
Step-by-Step Solution
Verified Answer
\[ \begin{align*} g(-1) &= 8, \ g(x+2) &= x^{2} - 6x - 19, \ g(-x) &= x^{2} + 10x - 3 \end{align*}\]
1Step 1: Evaluate \(g(-1)\)
To evaluate \(g(-1)\), substitute \(-1\) into the function \(g(x) = x^{2}-10x-3\). This gives: \(g(-1) = (-1)^{2}-10(-1)-3 = 1 + 10 - 3 = 8\)
2Step 2: Evaluate \(g(x+2)\)
To evaluate \(g(x+2)\), substitute \((x+2)\) into the function \(g(x) = x^{2}-10x-3\). This gives: \(g(x+2) = (x+2)^{2}-10(x+2)-3 = x^{2} + 4x + 4 -10x - 20 - 3 = x^{2} - 6x - 19\)
3Step 3: Evaluate \(g(-x)\)
To evaluate \(g(-x)\), substitute \(-x\) into the function \(g(x) = x^{2}-10x-3\). This gives: \(g(-x) = (-x)^{2}-10(-x)-3 = x^{2} + 10x - 3\)
