In Problems 1–6, use ZERO (or ROOT) to approximate the smaller of the two x-intercepts of each equation. Express the answer rounded
to two decimal places.
1. y = x? + 4x + 2
4. y = 3x? + 5x + 1
2. y = x? + 4x – 3
3. y = 2x? + 4x + 1
5. y = 2r – 3x – 1
6. y = 2x? – 4x – 1
I need help with #22, and #24. For those questions I need you to explain to me as you solve step by step and show me how to do it and the formulas you used. Thank You, for you service.
1. Use a linear approximation to approximate v143. (Be sure to show enough work so I can tell
you're using a linear approximation and not just hitting some buttons on your calculator!)
