Answer:
(-∞, 6]
Step-by-step explanation:
The leading coefficient is negative, so this is a downward facing parabola.
The vertex is at (-7, 6).
Therefore, the range is y ≤ 6, or in interval notation, (-∞, 6].
Answer:
648 m
Step-by-step explanation:
if i understand correctly you're multiplying all these number together. so 9 times 6 is 54. 54 times 3 is 162. 162 times 4 is 648.
Answer:
f(1) = 3
Step-by-step explanation:
f(t) = t² - 1t + 3
we want to find f(1)
all we have to do is replace the t's with 1 and evaluate
f(1) = (1)² - 1(1) + 3
evaluate exponent 1² = 1
f(1) = 1 - 1(1) + 3
multiply
f(1) = 1 - 1 + 3
subtract
f(1) = 3
