Agraph of 2 functions is shown below.

graph of function f of x equals 2 multiplied by x plus 1 and graph of function g of x equals x cubed plus 2 multiplied by x squared minus x minus 2

which of the following is an approximate solution for f(x) = g(x)?

a) x = −2
b) x = 0
c) x = −1
d) x = 1

The approximate solution for f(x)=g(x) is x= -1.

Step-by-step explanation:

Given  two functions are f(x) and g(x)

f(x)=

Therefore, f(x)= 2x+1

g(x)=

Therefore, g(x)=

From the given graph we can see that two functions are intersect to each other at points (1.46, 3.92) , ( -0.76, -0.52) and ( -2.7,-4.3).

It means the graph of two functions intersect at

x=1.46

x= -0.76

x=-2.7

The approximate value of

x=1.46=1.5

x=- 0.76=-1

x=-2.7=-3

Hence, f(x)=g(x) at x=-1
