I’m pretty sure your answer is E
Answer:
equal to
Step-by-step explanation:
1/3 = 3/9
1/3 = 1*3/3*3 = 3/9
Answer:
C.
f(x) = 8*(x - 1)²
f(x) = 8x² - 16x + 8
Step-by-step explanation:
vertex form:
f(x) = a*(x - h)² + k
where (h, k) is the vertex of the parabola
In this case, the vertex of the parabola is at (1, 0). Replacing this information into the equation we get:
f(x) = a*(x - 1)²
The parabola passes through point (2, 8). Replacing this information into the previous equation we get:
8 = a*(2 - 1)²
8 = a
Then, the final equation is:
f(x) = 8*(x - 1)²
Expanding the quadratic term and applying distributive property:
f(x) = 8*(x² - 2x + 1)
f(x) = 8x² - 16x + 8
Positive 6.8, because when numbers are next to each other with a parathesis being the only thing between them, all you have to do is multiply. Because they are both negative as well they'll cancel out or make the product/answer positive.
