Which equation represent the graphed function
UkoKoshka [18]

Answer:

C

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (4, - 1) ← 2 points on the line

m = \frac{-1+2}{4-0} = \frac{1}{4}

note that the line crosses the y-axis at (0, - 2) ⇒ c = - 2

y = \frac{1}{4} x - 2 ← equation of line

PLEASE ANSWER ASAP *picture attached*
SVETLANKA909090 [29]

Answer:

x^{2} -2x-8

Step-by-step explanation:

(f g)(x) is equal to f(x) times g(x).  So you just need to multiply both of the equations together.  Use the foil method to multiply (x+2)(x-4)

(fg)(x)=f(x)*g(x)\\\\(fg)(x)=(x+2)(x-4)\\\\(fg)(x)=x^{2} -4x+2x-8\\\\(fg)(x)=x^{2} -2x-8\\

I have attached an image to better explain the foil method

If the square of twice a number is 81, what is the number? I tried doing 2x^2=81 but that did not come out to the answer 4.5,-4.
Vlada [557]
If the number is n then

square of 2 times a number
square of 2n
(2n)²
that was your mistake, because (2n)²=4n², not 2n²

the result is 81
(2n)²=81
square root both sides
remember positive and negative roots
2n=+/-9
divide by 2
n=+/-4.5

n=4.5 or -4.5
