Determine whether the shapes of the following graphs of quadratic function is u or n a ) f(x) = x² - 4x + 1

see explanation

Step-by-step explanation:

Given a quadratic in standard form

f(x) = ax² + bx + c : a ≠ 0

• If a > 0 then minimum value U

• If a < 0 then maximum value ∩

f(x) = x² - 4x + 1 ← is in standard form

with a = 1 > 0

Thus f(x) = x² - 4x + 1 has a minimum value U

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
