QuestionCalculate $f(2)$ for the function $f(x)=x^{2}+3x-7$ .

Studdy Solution

STEP 1

Assumptions1. The function is given as $f(x)=x^{}+3 x-7$ . We need to find the value of the function when $x=$ , i.e., $f()$

STEP 2

To find the value of the function for a specific value of $x$ , we substitute that value into the function. In this case, we substitute $x=2$ into the function.
$f(2) = (2)^{2}+(2)-7$

STEP 3

First, we calculate the square of2.
$(2)^{2} =$ So, the equation becomes $f(2) =+3(2)-7$

STEP 4

Next, we multiply3 by2.
$3(2) =6$ So, the equation becomes $f(2) =4+6-7$

STEP 5

Finally, we perform the addition and subtraction operations.
$f(2) =4+-7 =3$ So, the value of $f(2)$ is3.

QuestionCalculate f(2)f(2)f(2) for the function f(x)=x2+3x−7f(x)=x^{2}+3x-7f(x)=x2+3x−7.

Studdy Solution

STEP 1

Assumptions1. The function is given as f(x)=x+3x−7f(x)=x^{}+3 x-7f(x)=x+3x−7 . We need to find the value of the function when x=x=x=, i.e., f()f()f()

STEP 2

To find the value of the function for a specific value of xxx, we substitute that value into the function. In this case, we substitute x=2x=2x=2 into the function.f(2)=(2)2+(2)−7f(2) = (2)^{2}+(2)-7f(2)=(2)2+(2)−7

STEP 3

First, we calculate the square of2.(2)2=(2)^{2} =(2)2=So, the equation becomesf(2)=+3(2)−7f(2) =+3(2)-7f(2)=+3(2)−7

STEP 4

Next, we multiply3 by2.3(2)=63(2) =63(2)=6So, the equation becomesf(2)=4+6−7f(2) =4+6-7f(2)=4+6−7

STEP 5

Finally, we perform the addition and subtraction operations.f(2)=4+−7=3f(2) =4+-7 =3f(2)=4+−7=3So, the value of f(2)f(2)f(2) is3.
