Exercises 105-108: Checking Symbolic Skills Find the formula for a quadratic function that satisfies the given conditions. 105. Vertex (3, 1) passing through the point (1, 9) 106. Vertex (-3, 4), passing through (–2, 1) 107. Vertex (–1, –5), passing through (0, –7) 108. Vertex (2, 1), passing through (0, 13)

Exercises 85-96: Checking Symbolic Skills (Refer to Example 4.) Solve the equation for y. Determine if y is a function of x. 85. y = x 86. y = 3x 88. 1- x = 9y2 + 5x * +y = y- 2 87. 2 – 4y? = x 89. 4x² + 3y = y + 1 3. 90. 91. 3y = 2x – y 92 . x + 3y 93. x² + (y – 3) = 9 94. (x + 2)° + (y + 1)² = 1 2.

5- -5 5 -5- Determine the values of a, b, c, and d so the function (a - a) (x + 1) (x + b) (x- c) (x + d) (x + 3) f (x) = correctly model the graph. (a, b, c, and d are all whole numbers) a = 5,

How do I find the find the axis of symmetry of a function?
