What else can I help you with?
Assume f of x equals 4x plus 8 and g of x equals 5 What is the value of g o f-1?
g(x) = 5. So whatever f(x) or f(-1) is, g of that is going to be 5.
What is gf 4 if f x equals 5x and g x equals 3x - 7?
f(x)=5x, g(x)=3x-7 gf(x)= = g(f(x)) = g(5x) = 3*(5x) - 7 = 15x-7 So gf(4) = 15*4-7=53
What does it mean when two functions are separated by a circle ex f circle g equals?
Conventionally, f o g is a way to represent the operation of function g followed by function f.So for example, suppose f(x) = x + 2 and g(x) = 3xthen f o g (x) = f[g(x)] = f(3x) = 3x + 2Note, though, that the "o" operator is not commutative.g o f (x) = g[f(x)] = g(x + 2) = 3*(x + 2) = 3x + 6 which is not the same as f o g(x).Such "nested" or "chained" functions are particularly useful in calculus (differentation and integration).
What are the rules of differentiation?
While no set of rules can handle differentiating every expression, the following should help. For all of the following, assume c and n are constants, f(x) and g(x) are functions of x, and f'(x) and g'(x) mean the derivative of f and g respectively. Constant derivative rule:d/dx(c)=0 Constant multiple rule:d/dx(c*f(x))=c*f'(x) Sum and Difference Rule:d/dx(f(x)±g(x))=f'(x)±g'(x) Power rule:d/dx(xn)=n*xn-1 Product rule:d/dx(f(x)*g(x))=f'(x)*g(x) + g'(x)*f(x) Quotient rule:d/dx(f(x)/g(x))=(f'(x)*g(x)-g'(x)*f(x))/f(x)² Chain rule:d/dx(f(g(x))= f'(g(x))*g'(x)
if f(x)=x+8 and g(x)=-4x-3 find (f-g)(x)?
To find (f-g)(x), we need to subtract g(x) from f(x). So, (f-g)(x) = f(x) - g(x). Substituting the given functions, we get (f-g)(x) = (x+8) - (-4x-3). Simplifying this expression, we get (f-g)(x) = x + 8 + 4x + 3 = 5x + 11. Therefore, (f-g)(x) = 5x + 11.
If f of x equals x plus 1 and g of f of x equals x what is g of x?
f(x)=x+1 g(f(x))=x f(x)-1=x g(x)=x-1
Assume f of x equals 4x plus 8 and g of x equals 5 What is the value of g o f-1?
g(x) = 5. So whatever f(x) or f(-1) is, g of that is going to be 5.
If hx equals f o g x and hx equals sqrt x plus 5 find gx if fx equals sqrt x plus 2?
g(x) = x + 3 Then f o g (x) = f(g(x)) = f(x + 3) = sqrt[(x+3) + 2] = sqrt(x + 5)
If f of x equals g of x does f prime of x equal g prime of x?
Yes
What is the derivative of f plus g of 3 and f times g of 3 given that f of 3 equals 5 d dx f of 3 equals 1.1 g of 3 equals -4 d dx g of 3 equals 7 Also please explain QUICK THANK YOU?
d/dx [f(x) + g(x)] = d/dx [f(x)] + d/dx [g(x)] or f'(x) + g'(x) when x = 3, d/dx [f(x) + g(x)] = f'(3) + g'(3) = 1.1 + 7 = 8.1 d/dx [f(x)*g(x)] = f(x)*d/dx[g(x)] + d/dx[f(x)]*g(x) when x = 3, d/dx [f(x)*g(x)] = f(3)*g'(3) + f'(3)*g(3) = 5*7 + 1.1*(-4) = 35 - 4.4 = 31.1
What is f of g of x if f of x equals x squared plus 3 and g of x equals x plus 3?
Let f ( x ) = 3 x 5 and g ( x ) = 3 x 2 4 x
If c varies jointly as f and g and c equals 27 and f equals 18 and g equals 6 find c when f equals 30 and g equals 10?
x = 75
What is the domain of the function G of F of x when F of x equals 8 minus x G of y equals square root of y G of F of x equals square root of 8 minus x?
x
Find gf of 5 if f of x equals x plus 1 and g of x equals 3 x - 2?
gf(5) = g(f(5)) = g(5+1) since f(x) = x+1 and then g(6) = 3*6 - 2 = 18 - 2 = 16
What is gf 4 if f x equals 5x and g x equals 3x - 7?
f(x)=5x, g(x)=3x-7 gf(x)= = g(f(x)) = g(5x) = 3*(5x) - 7 = 15x-7 So gf(4) = 15*4-7=53
Are the functions F of x equals x-1 and g of x equals x2-1 over x plus 1 the same explain.?
f(x) = x - 1g(x) = (x2 - 1)/(x + 1) = (x - 1 )(x + 1)/(x + 1) = x - 1therefore, f(x) = g(x)
