Answer:
80
Step-by-step explanation:
first, put in (5x-4) for the x in g(x).
g(f(x))=(5x-4)^2 -1
now, FOIL and simplify.
25x^2-40x+16-1
25x^2-40x+15
now, plug in -1 for x.
25(-1)^2-40(-1)+15
25+40+15
80

Step-by-step explanation:
Pemdas

exponents
multiplication so
exponents
c^0.5
so 0.5=1/2 and if you have
x^(z/t)=
![\sqrt[t]{x^z}](https://tex.z-dn.net/?f=%20%5Csqrt%5Bt%5D%7Bx%5Ez%7D%20)
so
c^1/2=
![\sqrt[2]{c^1} or \sqrt{c}](https://tex.z-dn.net/?f=%20%5Csqrt%5B2%5D%7Bc%5E1%7D%20or%20%20%5Csqrt%7Bc%7D%20%20)
so
multiplication
-9 times √c is the answer or more commonly written as
-9√c
