Answer:
1st option
Step-by-step explanation:
From the graph the zeros are x = - 3 and x = 1 , then the corresponding factors are
(x + 3) and (x - 1) , so
y = a(x + 3)(x - 1) ← a is a multiplier
To find a substitute a point on the graph into the equation
Using (0, - 1.5 ) , then
- 1.5 = a(3)(- 1) = - 3a ( divide both sides by - 3 )
0.5 = a
Then
f(x) = 0.5(x + 3)(x - 1)
5x²y²+10x²-7y²-14
Factor 5x² and -7 from the expression to get:
5x²(y²+2)-7(y²+2)
Factor out y²+2 from the equation
(5x²-7)(y²+2)
4¹ = 4
4² = 16
4³ = 64
4⁴ = 256
(4⁵ = 1,024)
9 - 18
5 - 10
1 - 2
Work —
First line:
y = 2 (9)
y = 18
Second line:
10 = 2x
5 = x
Third line:
y = 2 (1)
y = 2
