Given f(x) = | – 5 – 4x| ,find the following:
jasenka [17]

Answer:

f(10) = 35 \\  \\ f( - 11) = 39 \\  \\ f(12) = 53 \\  \\ f(2) = 13

Step-by-step explanation:

f(x)  =  | - 5 - 4x|

To solve for the following substitute the value of x in the brackets into the above formula and solve for the value of x

<u>NB</u><u>:</u><u> </u> Absolute value of a negative number is the same number but positive.

So we have

f( - 10) =  | - 5 - 4( - 10)|  \\  =  | - 5 + 40|  = 35 \\  \\ f( - 11) =  | - 5 - 4( - 11)|  \\  =  | - 5 + 44|  = 39 \\  \\ f(12) =  | - 5 - 4(12)|  \\  =  | - 5 - 48|   \\  =  | - 53|  = 53 \\  \\ f(2) =  | - 5 - 4(2)|  \\  =  | - 5 - 8|  =  | - 13|  \\  = 13

Hope this helps you
