Answer:
f(x) = x² + 4x + 3
Step-by-step explanation:
Here in this problem, we have to find the quadratic function that has x = - 1 and x = - 3 as the only two real zeros.
So, from the above condition, we can say that (x + 1) and (x + 3) are the only two factors of the function.
Therefore, the function will be f(x) = (x + 1)(x + 3), such that if the function is zero, then the solutions will be x = - 1 and x = - 3.
Hence, f(x) = x² + 4x + 3 (Answer)
First multiply the original price by the discount. (250.99 x .78 = 195.7722)
Then subtract that number from the original. (259.99 - 195.7722 = 55.2178)
Then round to 2 decimals because dealing with money.
Answer: $55.22
P= 2(x+1) + 3(x-8)
= 2x+2+3x-24
= 5x-22
If you are trying to name them the first and 2nd one are cones, the third is a triangular pyramid and I believe the last one is called a square pyramid
