CSU Math Placement Exam with verified solutions 2024
slope-intercept form - answer y = mx + b
slope formula - answer m = (y₂- y₁) / (x₂- x₁)
point slope form - answer y - y₁ = m(x - x₁)
standard form - answer Ax + By = C
distance formula - answer d = √[( x₂ - x₁)² + (y₂ - y₁)²]
equation of a circle - answer (x - h)² + (y - k)² = r² where (h,k) is the center and r is the radius
absolute value piece wise function - answer |x| = { x if x >or= 0 { -x if x < 0
FOIL - answer First, Outer, Inner, Last
what does i equal? - answer square root of -1
i^2 - answer - 1
i^3 - answer - i
i^4 - answer 1 quadratic formula - answer x = -b ± √(b² - 4ac)/2a
vertex form - answer y = a(x - h)² + k
vertex - answer (-b/2a , -b² - 4ac/4a)
basic laws for working w/ exponents - answer i) (A^N)(A^M) = A^N+M
ii) (A^N)^M = A^NM
iii) (AB)^N = (A^N)(B^N)
iv) A^0 = 1
v) A^-N = 1/A^N
vi)(A/B)^N = (A^N) / (B^N)
rational exponents and radicals - answer ^n√a = a^(1/n)
^n√a^m = a^(m/n)
square root reminder - answer after finding the square root:
√64 = x
± 8 = x -> NOT just 8
|ax - b| > c - answer ax - b > c
OR
ax - b < c
graphing on a plane - answer **make a table of values
ANGLES - answer clockwise = negative
counterclockwise = positive
