The polynomial function represented by the data is equal to D. f(x) = −x² + 10.
<h3>How to determine the
polynomial function?</h3>
In order to determine the polynomial function represented by the data, we would substitute the value of x (-3) into the given set of functions as follows:
For option A, we have:
f(x) = 6x + 15
f(-3) = 6(-3) + 15
f(-5) = -18 + 15
f(-5) = -3 (False).
For option B, we have:
f(x) = -6x - 45
f(x) = -6(-3) - 45
f(x) = 18 - 45
f(x) = -27 (False).
For option C, we have:
f(x) = x² - 40
f(x) = -3² - 40
f(x) = 9 - 40
f(x) = -31 (False).
For option D, we have:
f(x) = −x² + 10
f(x) = −(-2)² + 10
f(x) = −9 + 10
f(x) = 1 (True).

Answer:
(c) x = 10
Step-by-step explanation:
The diagonals of a square cross at right angles, so the measure of angle KNJ is 90°.
90 = 10x -10
100 = 10x . . . . . add 10
10 = x . . . . . . . . divide by 10
The value of x is 10.
Answer:
Step-by-step explanation:
3x < 4 - 1 or x > 31/9
3x < 3 or x > 31/9
x < 1 or x > 31/9
Answer:
y = 182
Step-by-step explanation:
Given y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 112 when x = 8
k = 
= 
= 14
y = 14x ← equation of variation
When x = 13, then
y = 14 × 13 = 182
