Answer: The correct option is option third .
Explanation:
The given equation are,
In the second equation the like terms are aligned, therefore, we have to aligened only first equation.
The first equation is,
Subtract 0.8 from both the sides.
Add 0.4y on both the sides.
So, after aligned the system of equation have two equations.
Both equation are show in third option, So third option is correct.
<u>Part 1</u>
The gradient of the line is , so the equation is .
This means the system is
<u>Part 2</u>
Substituting in the coordinates (-3,11) and (2,1) into the equation of the parabola,
Subtracting the equations, we get 10=5a, and thus a = 2
Substituting a = 2 back into the system, we get b = -7
<u>Part 3</u>
The equation of the parabola is , and the turning point is at . Therefore, the value of y is -7
Answer:
g(x) = x² + 5x + 2
Step-by-step explanation:
If a function is f(x) = x²
And this function is shifted 4 units left then the rule to be followed is,
g(x) = f(x + 4)
Following the same rule,
For a function f(x) = x² - 3x - 2 when shifted 4 units to the left,
g(x) = f(x + 4)
g(x) = (x + 4)² - 3(x + 4) - 2
= x² + 8x + 16 - 3x - 12 - 2
= x² + 5x + 2
Therefore, g(x) = x² + 5x + 2 will be the transformed function.
