3 - 5x = 2 Add three to both sides
-5x = 5 Divide both sides by -5
x = -1
Answer:
f(x)= x2 -4
Step-by-step explanation:
it is because it has no complex roots
Answer:
The phase shift:
1 unit to the right and 1 unit up
Step-by-step explanation:
∵ y = 1 + sin2(x - 1)
∴ y = 1 + sin(2x - 2)
∵ y = Sin(Bx - C) + D
∵ The vertical shift is D
∴ The horizontal shift is -C/B
∴ The vertical shift is 1 unit up
∴ The horizontal shift is --2/2 = 1 ⇒ 1 unite to the right
