Answer:
see explanation
Step-by-step explanation:
To evaluate f(- x) substitute x = - x into f(x)
f(- x) = (- x)² + 2(- x) + 3 = x² - 2x + 3
-----------------------------------------------------
- f(x) = - (x² + 2x + 3) ← distribute parenthesis by - 1
= - x² - 2x - 3
-----------------------------------------------------------
- f(- x) ← substitute f(- x) from above
= - (x² - 2x + 3) ← distribute parenthesis by - 1
= - x² + 2x - 3
In a quadratic function, y = a(x²) the smaller the coefficient "a", the larger is the parabola:
From widest to narrowest:
1) y=1/3x² (Widest)
2) y= -1/2x² (Wider)
3) y=-9x² (narrowest)
I dont know im trying to figure that out
Answer:
x=-6
Step-by-step explanation:
2x-1=3x-7
2x-3x=-7+1
x=-6
