Answer:
f (x) = a(x - h)2 + k, where (h, k) is the vertex of the parabola.

To write the coefficients of the 8 terms, either start with a combination of 7 things taken 0 at a time and continue to 7 things taken 7 at a time or use the 7th row of Pascal’s triangle.
For the first term, write x to the 7th power and 3 to the 0 power. Then decrease the power on x and increase the power on y until you reach x to the 0 and y to the 7.
Simplify by evaluating the coefficients and powers of 3.
Answer:
tan <F = 1/√3
Step-by-step explanation:
Using the SOH CAN TOA identity
tan theta = opposite/adjacent]
tan < F = GE/FG
Get GE
Using pythagoras theorem
GE² = 14² - (7√3)²
GE² = 196 - 147
GE² = 49
GE = 7
tan<F = 7/7√3
tan <F = 1/√3
