Question

If f(x)=2x-6
f(2)
can someone tell me how to solve it! please

Answer 1

where you see an \(x\) put a \(2\) and compute
\[f(2)=2\times 2-6\]

Answer 2

that's it!

Answer 3

yeh and remember multiply first :D

Answer 4

im lost right now . >_<

Answer 5

yeah that's it!

Answer 6

if you can compute
\[2\times 2-6\] then you can do this

Answer 7

your looking for f(2), so wherever x is replace it with 2 and u get f(2)=(2×2)−6

Answer 66

alright brother name and the name is Abdoulkarim

Answer 67

changed each equation to function notation and then find the value
equation function notation find value for...
y=3x^2-2 f(2)

Answer 68

pleasure meeting ya see ya around

Answer 69

so the notation is going to be f(2)=3x^2-2
(3x4)-2=?

Answer 70

can u do it step by step so i'll understand it better and understand how to work the others please!

Answer 71

ok

Answer 72

since the equation is already already in its formal of y=.....,
all you have to is replace y= to f(x), which will give you f(x)=3x^2-2
and wherever there is an x replace it with 2 since your looking for f(2)

Answer 73

then youll get f(2)=3(2)^2-2
fallow the rule of pemdas to solve in this case exponent first, so (3x4) and then -2

Answer 74

oh ok so is that equal 10 or im lost?

Answer 75

yeap
