Problem 1
For functions like f(x), the input is x and the output is f(x).
If x = 7, then f(7) = 12 has the input 7 and output 12.
Therefore the ordered pair is (7, 12) which is the answer
=====================================================
Problem 2
Replace every x with 3 and simplify
f(x) = 3*x
f(3) = 3*3
f(3) = 9
The input x = 3 leads to the output y = 9. Recall that y = f(x).
So (3,9) is the answer here.

Answer:
14.4222
Step-by-step explanation:
Distance between two points = √(x₂ – x₁)² + (y₂ – y₁)²
Distance between two points = √(6 – -2)² + (-5 – 7)²
√(6 – -2)² + (-5 – 7)²
√8² + (-12)²
√64 + 144
√208
14.4222

Answer:
A altura máxima é 5
Step-by-step explanation:
Matematicamente, a altura máxima pode ser obtida
A altura máxima é simplesmente o vértice da parábola
Começamos diferenciando a função Isso será -8x
Agora, defina -8x como 0
Isso significa que x = 0
Agora, substitua x = 0 de volta na equação temos
f (0) = -4 (0) ^ 2 + 5
f (0) = 5
A altura máxima é 5
