Answer:
yes it is a function
the domain is (-3, 8]
the range looks like (-5, 2.5]
Step-by-step explanation:
using the vertical line test, you can find that it is a function
the domain is all the x values between -3 and 8. -3 is not included since there is an open circle
The range is all the y values
<span>Curtis
threw 15 darts at a dartboard. 40% of his darts hit the bull's-eye.
Let’s find out how many darts did not hit the bull's-eye.
=> 15 darts = 100%
=> 40% of 15 hits bull’s eye.
Now let’s solve:
=> 40% / 100% = .40
we need to get the 40% value of 15 to know how many darts was able to hit bull’s
eye.
=> 15 * .40 = 6 darts
Thus, out of 15, 6 of the darts hit bull’s eye,.</span>
Answer is 602 because we just take 301 times 2 because there is only two types of book in company and 301 book are ordered in each type so we just take 2 times 301
Axis of symmetry = x = -b/2a
where y = ax² + bx + c
f(x) = x² + 6x - 1 ⇒ a = 1 ; b = 6 ; c = -1
x = -(6)/2(1) = -6/2 = -3
g(x) = -x² + 2 ⇒ a = -1 ; b = 0 ; c = 2
x = -0/2(-1) = 0/-2 = 0
h(x) = 2x² - 4x + 3 ⇒ a = 2 ; b = -4 ; c = 3
x = -(-4)/2(2) = 4/4 = 1
least : f(x) = x² + 6x - 1 ; axis of symmetry is -3
middle : g(x) = -x² + 2 ; axis of symmetry is 0
greatest : h(x) = 2x² - 4x + 3 ; axis of symmetry is 1
The answer is the letter C
