The value of the function f(-2), x and F(3) +f(0) are -7, 9 and 0 respectivey
Functions and values
Given the following equation expressed asx:
f(x) = 2x - 3
For f(-2)
f(-2) = 2(-2) - 3
f(-2) = -4-3
f(-2) = -7
If the function f(x) = 15, hence;
2x - 3 = 15
2x = 18
x = 9
For F(3) +f(0)
F(3) +f(0) = 2(3) -3 + 2(0) - 3
F(3) +f(0) = 3 - 3
F(3) +f(0) = 0
Hence the value of the function F(3) +f(0) is 0
