answer:
Now I know My ABC next time won't you sing with me.
Substituting, we have
... f(x+4) = (x+4)² + 8(x+4) +7
... = x² +8x +16 +8x +32 +7
... = x² + 16x + 55
Subtracting the original, we have
... f(x+4) - f(x) = (x² +16x +55) -(x² +8x +7)
... f(x+4) - f(x) = 8x +48
You can find an axis of symmmetry of quadratic function by using this formula:
An axis of f(x):
Of g(x):
Of h(x):
At least to greatest you've got -3, 0, 1 so f(x), g(x), h(x). Answer a
