WILL GIVE BRAINLIEST! 3. Solve the equation x2 – 2x – 3 = 0 by graphing.

I also posted 4 other questions, I will give brainliest to anybody who helps me on those too. You don’t have to do all just at least one.

x = -1,3 I think

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
