f(x) = 4x² + 5x – 2
g(x) = 5x – 2x² – 3x + 4
h(x) = f(x) + g(x) = (4x² + 5x – 2) + (5x – 2x² – 3x + 4)
(4x²+5x–2) + (5x–2x²– 3x+4) = 4x² + 5x – 2 + 5x – 2x² – 3x + 4 = 2x² + 7x + 2
Answer: h(x) = 2x² + 7x + 2
Answer:
a
Step-by-step explanation:
Answer: B 386
(7*15)*2 + (7*4)*2 + (15*4)*2
= 210+120+56
= 386
Basically think of linear functions/equations as something with a constant value or consistent result. For example: (Attachment)
