After solving the values f(x) = 8 – 10x and g(x) = 5x 4, the value of (fg)(–2) will be -168.
function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and dependent variable.
f f(x) = 8 - 10x and g(x) = 5x + 4, what is the value of (f9)(-2)?
Replace x in each equation with -2:
f(x) = 8 -10(-2) = 8 +20 = 28
g(x) = 5(-2) + 4 = -10 + 4 = -6
Now multiply the two"
28 * -6 = -168
The answer is -168
