We have to start with a number $x$ , compute $f(x)$ , and then use this result as input for $g(x)$

When you give $x$ as input to $f$ , it returns $-x^2-1$ :

$x\mapsto f(x)-x^2-1$

Now, $g(x)=x+5$ simply means that $g$ will return its input plus five.

In this case, the input is $f(x)$ , so we have

$g(f(x))=f(x)+5 = -x^2-1+5=-x^2+4$

There are 75 boys in the sixth grade. The ratio of girls to boys is 7 to 5. How many girls are there in sixth grade?

kolbaska11 [484]

There are 105 in 6th grade because there are 75 boys right? So it said the ratio of girls is 7 and the ratio of boys is 5 so I divided 75 to 5 = 15 and I multiply 7 to 15 and got 105 girls.

Given f(x) = x − 7 and g(x) = x2 . Find g(f(−1)).

ivann1987 [24]

Answer:

64

Step-by-step explanation:

$g(f(-1))$ can be found by first finding $f(-1)$ then taking that result and putting it into the function $g$ .

$f(-1)$ means we are going to take the expression $x-7$ and evaluate it for $x=-1$ :

$-1-7$

$-8$

So $f(-1)=-8$ .

So we have this so far:

$g(f(-1))=g(-8)=(-8)^2=64$ .

$g(-8)$ was found by replacing $x$ in $x^2$ with $-8$ .
