Re-write the quadratic function below in Standard Form
y = -(x + 8)(x + 7)
1 answer:
Answer:
y = - x² - 15x - 56
Step-by-step explanation:
y = - (x + 8)(x + 7) ← expand factors using FOIL
= - (x² + 15x + 56) ← distribute parenthesis by - 1
y = - x² - 15x - 56 ← in standard form

Step-by-step explanation:
Apply exponent rule:
![\sqrt[n]{a} =a^{\frac{1}{n}}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%7D%20%3Da%5E%7B%5Cfrac%7B1%7D%7Bn%7D%7D)
![\implies \sqrt[11]{12}=12^{\frac{1}{11}}](https://tex.z-dn.net/?f=%5Cimplies%20%5Csqrt%5B11%5D%7B12%7D%3D12%5E%7B%5Cfrac%7B1%7D%7B11%7D%7D)

For number three they are all equal
Answer:
#1 and #3
Step-by-step explanation:
Lna^b = blna
let y = lne^e
so y = lne^e = e lne
lne = 1
y = e which is a constant (Euler's number) ~= 2.718
For Euler's number estimating methods request in a comment.
