SOLUTION: f(x)= 4x - 3 g(x)= x^3 + 2x Find (f-g)(4) - Algebra …
You can put this solution on YOUR website! (f-g)(4) means f(4) - g(4). So we need to calculate f(4) and g(4) first
SOLUTION: find (f*g)(-4) and (g*f)(-4) f(x)=-2x-1; g(x)=(x^2)+5
f g(x) and f*g(x) are entirely different things. f*g(x) means to multiply the expressions together, but f g(x) means to substitute what g(x) equals for x in what f(x) equals. To get the little circle on here, type this &# 9702; but don't skip a space between the # and the 9.
SOLUTION: Let f(x)= x^2 - 16 and g(x)= x - 4. What are f*g and f/g ...
f/g means divide the functions (x^2-16)/(x-4), but the numerator is a difference of squares, (x+4)(x-4), and the last cancels the denominator. f/g=(x+4) ===== Domains of a composite function are the domains that satisfy both. f(x) has domain of all reals. g(x) does too. Their composite domain is all reals ===== In the second, the denominator is ...
SOLUTION: f(x) = 3x - 7 and g(x) = -2x - 6 Find ( f o g) (4) please ...
The notation (f o g)(x) is really the same as f(g(x)) So saying (f o g)(4) means we want to compute f(g(4)) First let's plug x = 4 into g(x), which is the inner function. g(x) = -2x-6 g(4) = -2(4)-6 g(4) = -8-6 g(4) = -14 So f(g(4)) gets updated to f(-14) after we replace the "g(4)" with "-14" Now let's compute f(-14) f(x) = 3x-7 f(-14) = 3(-14)-7
SOLUTION: Evaluate the function for f (x) = x + 3 and g (x) = x2 − …

: Let f(x) = 2x + 1 and g(x) = x^2 - 4 and find the following:
You can put this solution on YOUR website! Let f(x) = 2x + 1 and g(x) = x^2 - 4 (fg)(x) has two meanings whether it is component wise multiplication or composition
write the expressions for (f-g)(x) and (f*g)(x) and evaluate (f+g)(4)
Question 1083424: Suppose that the functions f and g are defined for all real numbers x as follows. f(x)=x+6 g(x)=4x+6
SOLUTION: Let f(x) = 4x - 7 and g(x) = 2x - 3. Find. (f*g)(4)
Let f(x) = 4x - 7 and g(x) = 2x - 3. Find. (f*g)(4) All we need to do is plug what f and g are into the multiplication problem. In terms of x (when x is in the domain of f and g), (f*g) is (4x-7)(2x-3). Multiplying this out, we have (4x-7)(2x-3) = 8x^2 - 26x + 21.
