Question

QueSLIUM
Functions f(x) = 5^x
-4 and g(x) = 1 + 2x are given. Determine (fog)(3).​

Answer 1

Step-by-step explanation:

f(x)=∣x∣ and g(x)=∣5x−2∣

∴fog(x)=f(g(x))=f(∣5x−2∣)=∣∣5x−2∣∣.

∴fog(x)=∣5x−2∣

Answer 2

Answer:

The answer is 125

Step-by-step explanation:

First of all find g(3) by substituting x=3 in g(x):

g(3)=1+2(3)

g(3)=7

Now substitute the value of g(3) in place of x in f(x):

f(g(3))=5^{7-4}

f(g(3))=5^3

f(g(3))=125
