You're right. Both (d) and (e) work. Just plug them into f(x) and you should get 2.
Do you know how to factor trinomials?2. Solve: 3t^2 + 5t - 12 = 0. How do you solve this algebraically (without using a graphing calculator)? I'm clueless, so I can't show work.
Answer: t = -3 or 4/3
Can somebody help me out with these questions?
In general: is an equation of a circle with as the centre and as the radius.I have a third one:
3. If (m, -2) is on a circle with center (-2,2) and a radius 9. Find the value of m.
So, we can deduce that your circle is given by:
Since (m, -2) is on the circle, simply plug them in:
