Evaluate the function.
p(x)=2/5x+1/2, when x is 3.
Those are fractions, by the way..
If you mean (2/5)x and not 2/(5x), the answer is 6/5 + 1/2 = 17/10
Okay thanks!(:
To evaluate the function p(x) = (2/5)x + 1/2 when x = 3, you need to substitute the value of x into the function and simplify the expression.
Step 1: Replace x with 3 in the equation p(x) = (2/5)x + 1/2.
p(3) = (2/5)(3) + 1/2
Step 2: Simplify the expression within the parentheses.
p(3) = (6/5) + 1/2
To add these fractions, they must have a common denominator. Find the least common denominator (LCD), which is 10 in this case.
p(3) = (6/5) * (2/2) + (1/2) * (5/5)
Now, both fractions have a denominator of 10.
p(3) = 12/10 + 5/10
Step 3: Add the fractions.
p(3) = (12 + 5) / 10
p(3) = 17/10
Therefore, the value of the function p(x) when x = 3 is 17/10.
