Solve the following:
1) F(x)= 3x^2 + 2x -5
2) F(x)= -24^2 - 1
3) F(x) =√ x +4
Graph the following:
1) F(x)= 3x^2 + 2x -5
2) F(x)= -24^2 - 1
3) F(x) =√ x +4
Solve the following:
1) (x -3) (x-6)> 0
2) (x^2 - 4)> 0
Simplify: giving f(x) = 3x^2 + 5, g(x)= x-4, h(x) = x +5
1) fog(x)=
2) goh(x)=
3) foh(x)=
4) (f + g)(x)
5) (g -h) (x)
6) (f - h) (x)

1) 5/x-5
2) √ 2x -2
3) 3x^2 -5
Simplify: 4√ 3 6√ 3/4√ 3
√ 50 +3√ 8 + 4√ 18
Determine f for each function using the switch and solve strategy. Check
that (f o f-1 ) (x) = x and visa versa .
1) f(x) = x^2 -1 for x≥ 0
2) f(x) = x^2 + 3 for x ≥0
3) f(x) = 1/x + 2 amd f-1 (x)= 1/x-2
