Answer:
f(4) = 4
Step-by-step explanation:
We have x = 4 so we use the middle line of the piecewise function since 0≤x≤4
f(x) = x
-4
f(x) = 4x - 12
Let x=2
f(2) = 4*2 - 12
= 8-12
= -4
334
10 × 4 × 7 = 280
3 × 3 × 6 = 54
280 + 54 = 334
3 = 92 degree 4 = 88 degree
3 = 45 + 47 = 92 degree
4 = 180 - 92 = 88 degree
