The answer to both should be 70. For 1, I’m fairly sure it’s 180 so subtract 110 to get 70. For 2, 8 equals 70 so 6 would also equal 70.

For f(x)=2-x and g(x)=4x^2+x+6, find (f×g)(x)
Dima020 [189]

Answer:

Our composed function is f(g(x)) = -4x^2-x-4.

Step-by-step explanation:

We are given two separate functions:

f(x) = 2-x

g(x) = 4x^2 + x + 6

We need to find the composition of (f \cdot g)(x). This is literally stating "f of g of x."

Therefore, we simply plug g(x) into f(x) and solve. We replace the x-value in the f(x) function with the entirety of the g(x) function and simplify.

f(g(x)) = 2 - (4x^2+x+6)\\\\f(g(x)) = 2 - 4x^2 + x + 6\\\\f(g(x)) = -4x^2 - x - 4

Our composed function is f(g(x)) = -4x^2-x-4.

<h3>Answer : y = ⅚x - 3</h3>

════════════════════

<h3>Known</h3>

x1 = 6

y1 = 2

x2 = (-6)

y2 = (-8)

════════════════════

<h3>Question</h3>

Equation of the line (y = mx + c)

════════════════════

<h3>Way to do</h3>

#First, you find the gradient (m)

m =  \frac{y2 - y1}{x2 - x1}  =  \frac{(( - 8) - 2)}{(( - 6) - 6)}  =  \frac{( - 10)}{( - 12)}  =  \frac{5}{6}

#Now use the formula of equation of the line

y - y1 = m(x - x1)

y - 2 = ⅚(x - 6)

y - 2 = ⅚x - 5

y = ⅚x - 5+2

y = ⅚x - 3
