Question

Given the function g(x) = −4x + 5, find g(−4).

Answer 1

g(−4).=-4(-4)+5=21

Answer 2

how bout this one Given the function f(x) = 2(x + 6), find x if f(x) = 22.

Answer 3

Put x = -4 in the the function:
g(-4) = -4(-4) + 5

g(-4) = 21...

Answer 4

Then put f(x) = 22

S0, 22 = 2(x + 6)
11 = x + 6

x = 5 is the answer...

Answer 5

i dont get wat happened to the 2

Answer 6

In simple way, divide by 2 both the sides,

22/11 = 2(x + 6)/2 So, the 2 will get cancelled leaving 11 = x + 6..
Getting or not??
