Use the ^ symbol (shift+6 on the keyboard) to signify an exponent. for example, for 2 to the third power, enter 2^3. the domain for f(x) and g(x) is the set of all real numbers. let f(x) = 5x2 − 4x and g(x) = 5x + 1. find f + g. incorrect feedback has been removed from the screen. fill in the blank text field 1

Solution

f(x) = 5 - 4x

and g(x) = 5x + 1

f + g is nothing but addition of f(x) and g(x)

Therefore, f + g = f(x) + g(x)

= 5 - 4x + 5x + 1

Simplify the like terms, here -4x and 5x are the like terms.

f + g = 5 + 1x + 1              [ 5x - 4x = 1x which is nothing but x]

f + g = 5+ x + 1

Thank you :)

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
