Mathematics

Digiron [165]3 years ago

hey there!!

Given :

f ( x ) = l 2x - 4 l , find f ( - 7 )

We will have to substitute the value of -7 instead of x

f ( -7 )  = l -14 - 4 l

f ( -7 ) = l -18 l

As the value in a mod shall always be positive, the answer would become 18

Hence, the required answer is 18

Hope my answer helps!!

The degree of the polynomial function f(x) is 3.
Schach [20]

We are given degree of the polynomial function = 3.

Because degree is 3, there should be three x-intercepts of the given graph of the polynomial.

We also given roots of the equation f(x)=0 are −2 , 0, and 3.

Therefore, x intercepts should be at:

(0,0), (-2,0) and (3,0).

<h3>In the given options third option shows x-intercepts at 0, -2 and 3.</h3><h3>Therefore, correct option is 3rd option.</h3>

If possible, choose k so that the following function is continuous on any interval:
Alexxx [7]
We need to cancel out the discontinuity in x = 4

In order to do that, factorize the numerator:
5x⁴ - 20x³ = 5x³(x-4)

This way, your function will be:
f(x) = <span>5x³(x-4) / (x-4)

and the two parentheses cancel out, leaving
</span>f(x) = <span>5x³ 
</span>
which at x = 4 gives:
f(4) = <span>5·4³</span> = 5 · 64 = 320

Therefore K = 320.

WILL MARK YOU BRAINLIEST!!!!!!
My name is Ann [436]

Answer:

y = 88

Step-by-step explanation:

Don't worry about the other stuff, just worry about what's in the triangle that has Y.

53°, 39°, and y°

the sum should be equal to 180 so add 53 adn 39 and subtract it from 180.

180 - (53 + 39) = y

180 - 92 = y

88 = y

Hope this helped! Pls Brainliest my answer! It would help amd mean a lot! ;)

valkas [14]

Answer: 16

Step-by-step explanation:

if we were to list all the factors of 64 and 144

64= 1,2,4,8,8,16,32,64

144= 1,2,3,4,6,8,9,12,12,16,18,24,36,48,72,144

therefore the GCF of 64 and 144 is 16
