Funksjonsuttrykket er \( f(x) = 15x \).

Solución

For å lage et funksjonsuttrykk \( f(x) \) som viser hvor mye Alex betaler for \( x \) passeringer av bomstasjonen, kan vi bruke følgende informasjon: - Alex betaler 15 kr for hver passering. - Antall passeringer er representert med \( x \). Funksjonsuttrykket kan derfor skrives som: \[ f(x) = 15x \] Her er \( f(x) \) den totale kostnaden i kroner, og \( x \) er antall passeringer.

Beyond the Answer

Funksjonsuttrykket for hvor mye Alex betaler for \( x \) passeringer kan skrives som \( f(x) = 15x \). Her representerer \( f(x) \) det totale beløpet han betaler, og \( x \) er antall passeringer. Jo flere passeringer han har, jo mer må han betale – så det blir en morsom måte å se hvordan regningen vokser! La oss si at Alex passerer bomstasjonen 10 ganger. Da kan vi enkelt finne ut hvor mye han må betale: \( f(10) = 15 \cdot 10 = 150 \) kr. Så neste gang han tar en tur, kan han lett legge til kostnaden basert på antall passeringer han planlegger!

6:10 26 GUIDELINES FOR MODELING WITH EQUATIONS 1. Identify the Variable. Identify the quantity that the problem asks you to find. This quantity can usually be determined by a careful reading of the question that is posed at the end of the problem. Then introduce notation for the variable (call it \( x \) or some other letter). 2. Translate from Words to Algebra. Read each sentence in the problem again, and express all the quantities mentioned in the problem in terms of the variable you defined in Step 1. To organize this information, it is sometimes helpful to draw a diagram or make a table. 3. Set Up the Model. Find the crucial fact in the problem that gives a relationship between the expressions you listed in Step 2. Set up an equation (or model) that expresses this relationship. 4. Solve the Equation and Check Your Answer. Solve the equation, check your answer, and express it as a sentence that answers the question posed in the problem. 1) Express the following quantity in terms of \( s \). The average of three test scores, if the first two scores are 66 and 84 and the third score is \( s \). 2) A cell phone company charges a monthly fee of \( \$ 10 \) for the first 1000 text messages and 10 cents for every additional text message.
