Question

If c(x) = 4x – 2 and d(x) = x2 + 5x, what is (c circle d) (x)? 4x3 + 18x2 – 10x x2 + 9x – 2 16x2 + 4x – 6 4x2 + 20x – 2

Answer 1

GIVEN :

If c(x) = 4x - 2 and $d(x) = x^2 + 5x$, what is $(c \circ d) (x)$ :

TO FIND :

The value of the composite function $(c \circ d) (x)$

SOLUTION :

Given functions are c(x) = 4x - 2 and $d(x) = x^2 + 5x$

Now we have to find the value of $(c \circ d) (x)$ :

$(c \circ d) (x)=c(d(x))$

By using the composite function formula :

$(f \circ g) (x)=f(g(x))$

$=c(x^2+5x)$

$=4(x^2+5x)-2$

$=4x^2+20x-2$

$(c \circ d) (x)=4x^2+20x-2$

∴ Option D) $4x^2+20x-2$ is correct

The value of the composite function $(c \circ d) (x)$ is $4x^2+20x-2$
