Question

Asked Oct 15, 2019

Use the function f(x)=x^2-4 and g(x)=2x+20 answer parts (a)-(g).

(a) solve f(x)=0

(b) solve g(x)=0

(c) solve f(x)=g(x)

(d) solve f(x)>0

(e) solve g(x)<_0

(f) solve f(x)>g(x).

(g) solve f(x)>-1

Step 1

Since, There are multiple number of subparts in the question, we are answering only the first three subparts.

(a) The given functions are

Step 2

Substitute *f*(*x*)=0 and solve for *x* as shown below:

Step 3

(b) Substitute *g*(*x*)=0 and solve for *x* ...
