Let f(x) = -2x - 7 and g(x) = -4x + 6. find ().

78

Step-by-step explanation:

Multiply f(x) and g(x) then evaluate for x = - 5

f(x) × g(x)

= (- 2x - 7)(- 4x + 6) ← substitute x = - 5 into the expression

= (10 - 7)(20 + 6)

= 3 × 26

= 78

For this case we have the following functions:

We must find By definition we have to:

So:

We apply distributive property keeping in mind that:

We evaluate in :

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
