(1 point) Suppose Simplify as much as possible: f f(1) Simplify as much as possible f(4) f(1) U Are f i and equal? f(4)

f(x) = 4 + 3x^2

f(1/4) = 4 + 3(1/4)^2 = 4 + 3/16 = 67/16

f(1) / f(4) = 4+3 / 4 + 64 = 7/67

f(1/4) and f(1) / f(4) are not equal

B) 1 / t+8 - 3

g(0) = 1/ 8 - 3 = -23/8

g(t) = 0

1/ (t+8) - 3 = 0

1/(t+8) = 3

1 = 3(t+8)

1 = 3t + 24

1 - 24 = 3t

-23 = 3t

t = -23/3
