Evaluate the function:<br><br> f(x)=x2−4x, find f(−3)

VikaD [51]

Answer:

f(-3) = 21

Step-by-step explanation:

To solve this, you can replace all x's with -3 and then solve to find the answer.

f(x) = x^2 - 4x

f(-3) = -3^2 - 4(-3)

f(-3) = 9 - (-12)

f(-3) = 21

Which equation has a constant of proportionality equal to 9 y=81/3x y=9x y=3x y==1/9x

aev [14]

Answer:

B) y = 9 x has Proportionality Constant = 9

Step-by-step explanation:

Two quantities P and Q are said to be PROPORTIONAL if and only if:

P ∝ Q ⇔ P = k Q ⇔ $k = \frac{P}{Q}$

Here, k = PROPORTIONALITY CONSTANT

Given : k = 9

Now, let us consider the given expressions in which x ∝y

y = 81/3 x

Here, $\frac{y}{x} = \frac{81}{3} = 27 \ne 9$

So, here Proportionality Constant ≠ 9

y = 9 x

Here, $\frac{y}{x} = 9$

So, here Proportionality Constant = 9

y = 3 x

Here, $\frac{y}{x} = 3 \ne 9$

So, here Proportionality Constant ≠ 9

y = 1/9 x

Here, $\frac{y}{x} = \frac{1}{9} \ne 9$

So, here Proportionality Constant ≠ 9

Hence, only y = 9 x has Proportionality Constant = 9
