Answer:

(fog)(x)=4x^2+1

Step-by-step explanation:

Assume g(x)=x^2

(fog)(x) is a composition of two functions such that (fog)(x)=f(g(x)).

Consider the function:

f(x)=4x+1

Replace x with g(x) into the equation:

f(g(x))=4\cdot g(x)+1

Substitute g(x)=x^2 on the right side of the equation:

f(g(x))=4\cdot x^2+1

Therefore, the expression for (fog)(x) is 4x^2+1.

Suppose f(x)=x^2+3 and g(x)=x-2 find (f-g)(x
SSSSS [86.1K]

Answer:

x^2-x+5

Step-by-step explanation:

(f-g)(x)=f(x)-g(x)

= (x^2 + 3) - (x - 2)   (Don’t forget the -1 multiplies to the x AND -2

= x^2 + 3 - x + 2

=x^2-x+5

f(-1)=(-1)^2-8(-1)+5

now solve

f(-1)=1+8+5

f(-1)=14

there is your answer! hope this helps! :)
