Answer:
f(x) = x² + 2x - 3
Step-by-step explanation:
From the graph the zeros are x = - 3 and x = 1
Thus the factors are (x + 3) and (x - 1) and
f(x) = (x + 3)(x - 1) ← distribute using FOIL
= x² - x + 3x - 3
= x² + 2x - 3
Answer:
33 °C
Step-by-step explanation:
The bigger number is the <em>maximum</em> temperature.
Let’s call it T₂.
Then T₂ = 31 °C
=====
The smaller number is the <em>minimum</em> temperature
Let’s call it T₁.
Then T₁ = -2 °C
=====
The difference be the maximum and minimum temperature is
Diff = T₂ -T₁ Insert the values
Diff = 31 – (-2)
When you see a minus sign followed by a negative sign, turn them both into plus signs.
Then
Diff = 31 + (+2)
Diff = 31 + 2
Diff = 33 °C
My answer is 119.am I right?
