Given,

f(x) = -2x + 4

g(x) = -6x - 7

To find,

The value of f(x) - g(x)

Solution,

The value of f(x) - g(x) is 4x + 11.

We can simply solve the given mathematical problem by the following process.

We know that,

f(x) = -2x + 4

g(x) = -6x - 7

Now,

f(x) - g(x) = (-2x+4) - (-6x-7)

= -2x - 4 + 6x + 7

= 4x + 11

Thus, the value of f(x) - g(x) is 4x+11.

Explanation:

in the part a take the f(x) as the normal equation but in the place of x put the equation of g , its as g is now x .

in part b its the exact same only that instead of the x in equation of g(x) the gave you a number to plug into the x

Let f(x)=-2x+4 and g(x)=-6x-7 find f(x) g(x) find f(g(4)) please help and show work-example-1
