Answer:

$x = -5,\: -\frac{4}{5}$

Step-by-step explanation:

$5x^2 +29x + 20=0$

$\implies 5x^2 +25x +4x+ 20=0$

$\implies 5x(x +5) +4(x+ 5)=0$

$\implies (x +5) (5x+ 4)=0$

$\implies (x +5) = 0,\:(5x+ 4)=0$

$\implies x = -5,\:x=-\frac{4}{5}$

$\implies x = -5,\: -\frac{4}{5}$

If f(x)=4x^2 and g(x)=x+1, find (fog)(x)

iren [92.7K]

Answer: The value of $(f_\circ g)(x)$ is $4(x+1)^2$ .

Step-by-step explanation:

Given: $f(x) = 4x^2 \text { and } g(x) = x+1$

To find: $(f_\circ g)(x)$

As we know it is composition function which means that g(x) function is in f(x) function.

So we have

$(f_\circ g) (x) = f[g(x)]$

$\Rightarrow( f_\circ g)(x)= f(g(x)) = 4(g(x))^2$

Now substitute the value of g(x) we get

$(f_\circ g)(x)= 4(x+1)^2$

Hence, the value of $(f_\circ g)(x)$ is $4(x+1)^2$ .
