F(x) = -(x + 8)² - 1
<span>The function (not its graph) decreases on interval [-8, ∞). It is a quadratic function in vertex form. That form makes it easy to pick out the one extremum, where x equals -8. The leading coefficient is negative, so the extremum must be a maximum. The function decreases as x increases from there. </span>
<span>Notice that I include the value -8 in the interval. The function does not have instantaneous decrease at that value, but that is not what it means for a function to be decreasing over an interval. </span>
<span>Let a and b be any two values on [-8, ∞), such that a < b. </span>
<span>-8 ≤ a < b </span>
<span>Then f(a) > f(b). Therefore, function f is decreasing on interval [-8, ∞).</span>
1. false because the GCF of 101 and 102 is 1 whereas the GCF of 33 and 99 is 33.
2. idk
3. false because the GCF of 1 and 2 is 1
Im honestly not sure but I’m thinking answer A?
Original price = $20
Markup percentage = 65
Markup amount = 0
What is the profit?
65% of 20 = $12
Therefore Markup amount = $12
Profit = Original price + markup amount
= $20 + $12
= $32
Answer:
Step-by-step explanation:
To find the inverse of a function, or in this case , switch the places of the x and y in the given function, then isolate y. (Remember that is another way of saying y.)
Thus, .
