Answer:
fgh(x)=4 -14
Step-by-step explanation:
when solving composite fuctions we go from the right to the left
meaning we replace the x in the g function with the entire h function
then replace the x in the f function with the entire new g function
h(x)=
g()=
-5
f(-5)=4(
-5)+6
f(-5)=4
-20+6
fgh(x)=4 -14
Answer:
Your answers would be:
x = 10 and x = -8
Step-by-step explanation:
Solve for the zeros:
x² - 2x - 78 = 2
Subtract both sides by 2.
x² - 2x - 80 = 0
Use the quadratic formula:
a = 1
b = -2
c = -80
Plug in and solve:
