If f(x) = 7x+6 and g(x)=8x-4 find f(g(-2))

Answer:

f(g(-2))=-134

Step-by-step explanation:

So we have the two functions:

f(x)=7x+6\text{ and } g(x)=8x-4

And we want to find f(g(-2)).

First, let's find g(-2):

g(-2)=8(-2)-4

Multiply:

g(-2)=-16-4

Subtract:

g(-2)=-20

Now, substitute:

f(g(-2))=f(-20)

Now, find the value of f(-20):

f(-20)=7(-20)+6

Multiply:

f(-20)=-140+6

Add:

f(-20)=-134

So:

f(g(-2))=-134

And we're done!

X^2-4x+c find the value of c
Sonbull [250]

Answer:

c = 4

Step-by-step explanation:

Given

x^2 - 4x + c

Required

Find c

The question is incomplete. However, I'll assume the expression is a perfect square.

To find c, we make use of the following formula

c = (\frac{b}{2})^2

Where

ax^2 + bx + c

By comparison with x^2 - 4x + c

a =1

b = -4

So, c = (\frac{b}{2})^2 becomes

c = (\frac{-4}{2})^2

c = (-2)^2

c = 4

<em>The value of c that makes the expression, </em>x^2 - 4x + c<em> a perfect square is 4 and the expression is: </em>x^2 - 4x + 4<em></em>
