Question

If f(x)= 10x - 26 then f(-1)=​

Answer 1

Answer:

10 * - 1 - 26

= - 10-26

= - 36

.... ....

Answer 2

Step-by-step explanation:

f(x) = x2 + 1

g(x) = x - 5

f(g(x)) = g(x)2 + 1 = (x-5)2 + 1

Can you finish it from here?

f(g(x)) = x2 - 10x + 26

g(f(x)) = f(x) - 5 = x2 + 1 - 5 = x2 - 4

f(g(x)) = f(g(x))

x2 - 10x + 26 = x2 - 4

Solve for x.
