Answer:
The last one
Step-by-step explanation:
K so first look at y intercept which is +5, so we eliminate A and C, then the graph opens up so the b in ax+bx+c has to be positive which is D
the point ( 0 ; 5 ) in on the curve
so f(0) = 5
choice between :
x² - 2x + 5 or x² + 2x + 5 then :
we have the point (1 ; 4)
with x² - 2x + 5
f(1) = 1² - 2*1 + 5 = 1 - 2 + 5 = 4
so it's correct
=> x² - 2x + 5 is the right one
