Find the inverse of each function (show work please)

Mathematics
1 answer:
netineya [11]3 years ago
5 0

To find the inverse function of a function, you rearrange for the x term (could be some other letter) and then swap the function and the x at the end. For example,

g(x)=15x-10 \Rightarrow x=\frac{g(x)+10}{15} and so,

g^{-1}(x) = \frac{x+10}{15}.

For part 3 we have

h(x)=\frac{x-12}{4} \Rightarrow x=4h(x)+12 and hence,

h^{-1}(x)=4x+12=4(x+3)

Can you do part 4 on your own?

PLEASE ANSWER ASAP
Vlada [557]

Answer:

c

Step-by-step explanation:

For an inverse function you take f(x) and turn that to y then you switch x and y. So you should start off with y= 5x -8. so then you switch x and y so x= 5y - 8. So then you solve. You subtract 8 from both sides and divide by 5 and you get F(x) inverse = x + 8/5

The Freeman family is barbecuing veggie burgers, corn cobs, and mushroom caps in their local park. If 3/8 of the items barbecued
algol [13]

Answer:

7/24

Step-by-step explanation:

Let

total items barbequed = 1

Veggie burgers = 3/8

Corn cobs =1/3

Mushroom caps = x

Veggie burgers + corn cobs + x = 1

3/8 + 1/3 + x = 1

9+8 /24 + x = 1

17/24 + x = 1

x= 1 - 17/24

=24-17 /24

= 7/24

x = 7/24

Fraction of barbequed items that are mushroom's is 7/24
