Question

Pre-cal I don’t understand much

Answer 1

`\Huge \boxed{{x=3}}`

`\rule[225]{225}{2}`

Explanation:

f(x) = 4x - 3

f(x) = 9

Substituting.

9 = 4x - 3

Adding 3 to both sides.

12 = 4x

Dividing both sides by 4.

3 = x

`\rule[225]{225}{2}`

Answer 2

33

Explanation:

f(x) = 4x-3

Let x= 9

f(9) = 4*9 -3

36-3

33
